Kernel 3.10.104/4.9.13 r8152 reset

Post by mad_ady » Wed Mar 01, 2017 6:59 pm

Hello all!
I am stumped because I get two recurring kernel problems on my XU4 which is supposed to be a NAS. The problems appear at random without any apparent connection to the XU4's load (e.g. I get crashes even when the XU4 is mostly idle).
My system runs Ubuntu 16.04.2 with kernel Linux aldebaran 3.10.104 #1 SMP PREEMPT Fri Feb 10 15:33:11 EET 2017 armv7l armv7l armv7l GNU/Linux. The kernel is taken from HK's git and compiled by myself in order to activate XFS support. All the other options are from its defconfig.

So, I get two issues from time to time (either once every 1-2 days or sometimes a few times in a couple of hours):
1. There is a USB bus hang/reset which causes eth0 to stop working (it's still seen by the system but no traffic exits through it and tcpdump can't receive anything
2. Sometimes I get a kernel spinlock hang which panics the kernel (I have an automatic reboot after 120s set for this one).

Last night, when watching a video with the missus (over Samba) I got both problems and was fortunate to have scripts and watchdogs in place to capture what I thought is relevant information. Let me walk you through it:

1. The serial console log shows the following messages. The USB hub resets, the HDD "fails" midpoint, but it's rediscovered as /dev/sdb and is automatically remounted (I mount it with autofs by uuid):

At this point the box is no longer accessible by network, so I had a script run some commands to see what was going on:

The dmesg command shows the following output:

Networking looks like this after the incident (eth0 is part of brlan0). Also, eth0 is connected to a gigabit router and is usually connected at gigabit speeds, but after the incident it reports back only 100Mbps:

It also reports it sees the link, but - I'm actually worried about this. I was thinking of using an ASIX USB2 adapter together with the internal network adapter and add them to a bond interface so that when the internal network fails I could have the bond switch to the backup interface and at least still have connectivity to the box. However, bonding checks mii link status to determine if an interface works and would not detect eth0 as not working. Not sure if there is a way to check differently...
It might be possible that even if this end reports 100/Full the other end is stuck at 1000/Full which could result in a lack of communication. I may try to force it to 1000/Full in case of disaster :)

lsusb reports everything ok after the incident (I think they're ok at least):

Code: Select all

    |__ Port 1: Dev 2, If 0, Class=Vendor Specific Class, Driver=asix, 480M

At this point, to get networking running again I need to restart the box. Sometimes a reboot is sufficient, other times it results in eth0 missing completely from the output and I would require a second reboot to get it to work again.

So, I rebooted via serial last night which lead me to the second problem - the kernel panic:

So, I'd like to ask:
1. What can I do about the ethernet not working after a USB bus reset? Can I shutdown and restart the USB bus with a GPIO command like on the C2 (by the way that works wonderfully for the C2!)? What about detection? I am currently running a watchdog based on ping in cron every 5 minutes to detect such issues and collect data before rebooting, but it feels horrible having the NAS crash when watching a movie - so far the XU4 has a low WAF (Wife Acceptance Factor) and I'd like to change that. :)
2. Can I do anything about the kernel crash? I can't tie it to anything specific so far. I can reduce the reboot timer, but I'd like to have a stable box. <rant> My previous NAS, a WD MyBook WhiteLight with only 128MB of RAM ran very stable, but was slow</rant>

I know about the 4.9 kernel and I've played with it, but, for me it's not an option yet because my HDD has an old (v4) XFS filesystem which apparently lost some support in newer kernels (>4.4). I can mount it, but when I try to write to the filesystem, I get a kernel oops. I may need to take the time to move my data elsewhere, reformat the HDD to a newer XFS version or to a different FS and copy it back before I can run 4.9 in production. Even if I took 1 month to put the XU4 through its paces doing the NAS conversion (and even tested with XFS), it seems I still run into issues and it's not a painless transition. So, 4.9 is definetly on the horizon - question is - can I do anything about the current 3.x?

Thanks

Re: Kernel 3.10.104/4.9.13 r8152 reset

Post by mad_ady » Mon Mar 13, 2017 5:33 pm

Ok, I've updated this topic and changed the title a bit to reflect new information.

So, I've moved to kernel 4.9.13 (from HK's repo) and I had been running it fine for a few days until I got the same network card reset problem.
This time, the problem manifested during light network traffic (streaming an MP3 file). I lost network connectivity to the box and it was only accessible via serial. I collected some logs and I ran tcpdump on the network interface and I was unable to receive any packets. I tried to see if it gets fixed by rebooting the router and it did not. Here is the output:

Mar 12 19:43:36 aldebaran bin/ping-watchdog.sh: Network is down!
Sun Mar 12 19:43:36 EET 2017

I ran a reboot via serial and the board rebooted, but it was unable to read the emmc so got stuck in the initramfs waiting for input. A second reboot (from initramfs) managed to get the board running again.

Regarding the network card problem - what are my options? Is it something that is particular to my board (e.g. hardware triggered?), or do other people see it? Next time this happens I'd like to run usbreset on that bus to see if the card can recover. This way I can write a watchdog that resets the adapter if the problem appears - hopefully sufficiently fast enough so that software buffers can absorb the downtime and the clients only see a small dip in actual traffic. I'll let you know if usbreset works next time this happens.

But, I'm curious if this is a known issue or not. Or if there are better ways of handling this.

Also, unrelated to this - if the system gets stuck while booting inside the initramfs (unfortunately I lost the boot log), is there a way to have it automatically reboot after a while - assuming it's in production and doesn't have a console attached?

@moderator - please move this topic under the 4.9 kernel section. I will continue with 4.9 from now on - it's more stable than 3.10 for me, and it's what I wanted anyway.

The driver in the 4.9 sources is "rather" old it's tagged with 2014 have you tried using a newer version?

Re: Kernel 3.10.104/4.9.13 r8152 reset

Post by crashoverride » Mon Mar 13, 2017 6:34 pm

I would suggest you start narrowing the scope of the problem:
1) Test the ethernet. Send randomly generated data (not from a hdd/emm/sd card) to a device. Does the ethernet still fail?
2) Test the HDD. Write randomly generated data to the data to the HDD (via USB3). Does the ethernet still fail?
3) Test the ethernet+HDD. Write randomly generated data to the HDD and send it out over ethernet. Does the ethernet still fail?

Other suggestions include simplifying your network configuration. Remove the bond/bridge. Does the ethernet still fail?

Re: Kernel 3.10.104/4.9.13 r8152 reset

Post by mad_ady » Mon Mar 13, 2017 7:17 pm

Thank you both for your suggestions.
In the mean-time I tested out the fesability of doing a USB reset via https://gist.github.com/x2q/5124616
The reset works, but unfortunately, the network card does not work anymore (can't receive traffic in tcpdump):

Code: Select all

sudo ./usbreset /dev/bus/usb/006/002

Code: Select all

[58713.466126] usb 6-1: reset SuperSpeed USB device number 2 using xhci-hcd
[58713.499753] r8152 6-1:1.0 eth0: Promiscuous mode enabled
I've ordered the board to reboot, but it's stuck on shutdown so it will need to be powered off manually when I get home tonight.

@crashoverride: I will remove the bond and bridge (eth0 was bound to the bridge. The bond was planned as a backup to add 2 NICs under the same IP). Previous tests (iperf) didn't trigger the issue, but I will leave it on for a few hours and see what happens. I'll let you guys know tomorrow.
Also - I've seen the USB3 hub reset when trying to get a xfs_metadump from the disk (reading metadata in a dump file), which did not affect the network card. So, I'd say they are independent.

Re: Kernel 3.10.104/4.9.13 r8152 reset

Post by mad_ady » Wed Mar 15, 2017 2:29 am

Ok, I removed my disk and its enclosure from the xu4 (and converted a spare c2 into a makeshift nas).
I reconfigured networking and got rid of bonding and bridges. I rebooted and tested bidirectional iperf (with iperf and all usb interrupts bound to the big cores) for an hour (164GB total traffic), at 1Gbps (~930Mbps, tcp) and I haven't seen any nic crashes.
I'm going to leave an iperf running tonight for many hours, maybe I can trigger something...

The network card problem hasn't resurfaced yet. I will try to hook-up the HDD again tomorrow, and re-run the iperf test to see if there is any difference.

Please test again on our Kernel 4.9.13-19 update.
USB 3.0 and Ethernet are quite stable now.

Thanks for the heads-up! The strangest thing happened since we last spoke. I ran the 4.9 kernel very stably for the past 13 days. No usb resets, no network issues with the same load as before. I made two changes since my last tests, but I'm not sure they're relevant:
1. I plugged in the usb3 cable from my HDD more forcefully (with a grudge) :)
2. I disabled usb quirks mode for the NIC and usb3 HDD (/sys/devices/platform/soc:/soc:usb3-0:/12000000.dwc3:/xhci-hcd.2.auto/usbX/quirks)

Maybe the first thing made a difference, maybe the gremlins in the system left. However I'm afraid to touch it at the moment, but I'll prepare the new kernel and swap it in my next unplanned maintenance window (e.g. power outage) and let you guys know if there are issues.

Re: Kernel 3.10.104/4.9.13 r8152 reset

I'm experiencing similar issue on Linux odroid 4.9.28+:

Code: Select all

[  246.510773] usb 4-1.1: reset SuperSpeed USB device number 3 using xhci-hcd
I've noticed that it happens specially when I'm receiving and sending lots of data from/to the external HD at the USB3 through the ethernet (for example, when Transmission torrent is downloading and uploading at full speed ~15MB/s).

I've tried replacing the USB cable with a shorter one, but the problem remains. Did anyone have a more concrete clue on the cause of the problem?

Thanks in advance!

Fortunately/unfortunately the problem hasn't reappeared for me and I had large transfers (with a rate of 10MB/s)

@joaofl

Same hang happens to me also when I transfer data to external USB3.0 hdd (I have two drives connected via a powered usb3.0 hub). When I use qbittorrent, the transfer simply hangs but the odroid is still reachable --> only a restart can resume transfer. Speed is about 30 MB/s On 3.10.x I have no such issue. So for me kernel 4.9 is a no go for now :(

I suspect @crashoverride was too lazy to type all that by himself and resorted to a script or copy/paste trickery - which nullyfies his statement
Also, he should know that run-off sentences are bad!

The resets you are seeing are for the USB storage device, not for the network interface (r8152). Doesn't look like the same issue. Check cable, try with a shorter cable or clean the USB ports.

On first screen there is a reset of the network during boot, during this resets of USB storage network interface stops working. I was cleaning usb ports last year, I have quite a long cable but my interface has extra power supply and non removable USB cable.
