USB controller dying under heavy IO load

Post by linuxtardis »

Hi all,

I would like to ask for help with Odroid-HC2 and the 5.4 kernel. I've been running on 4.14 so far and I/O has been rock solid there (110 days uptime!). I tried to update to 5.4 few times. Unfortunately, every time I tried it I got hit by a kernel bug. When the system is under heavy I/O load, the SSD disappears from the system.

I can more or less reliably trigger this by running btrfs scrub on an INTEL SSDSC2KG240G8. I managed to capture this log on the serial line:

Is there anything I can do about this?

Thank you for any help and with regards,

I'm using Ubuntu 20.04 and the official kernel from http://deb.odroid.in/5422-s/. The 4.14 kernel comes from the 18.04 version and it works even under 20.04, but I've noticed that there have been no updates since September.

I've managed to complete a btrfs scrub using the latest 4.14 kernel from the bionic branch, so the SSD/HW itself shouldn't be the cause.

We don't manage the Kernel 4.14 anymore due to our limited resources.

We've run a few XU4 and HC2 devices with Kernel 5.4 + Ubuntu 20.04 for several months but there was no such issue.
We used only EXT4 file system. But, I'm not sure if the issue is related to the file system or not.

BTW, did you use the UASP mode on Kernel 4.14? or the legacy mass-storage mode?

Thank you for your quick reply, it seems that UASP is used on both kernel versions. This is the relevant section of `usb-devices` command output from 4.14; on 5.4 the driver is uas too:

I've noticed that I had the RAM overclock active. I've disabled it but unfortunately the crash still occurs. This time I got a different error:

Re: USB controller dying under heavy IO load

After doing some boot.scr/flash-kernel hacks, I managed to boot the 5.10.0-6-armmp kernel from Debian. Unfortunately the crash happens there too:

It looks like a maiinline regression between 4.14 and 5.4. I have now booted Debian 4.9.0-15-armmp (so without non-mainline code) and btrfs scrub finished without problems (in UAS mode).

Debian kernel 4.19.0-16-armmp is also failing to finish the scrub.

I'm trying to bisect the issue using the mainline kernel; it seems that the issue was introduced between the 4.18 and 4.19 releases.

Re: USB controller dying under heavy IO load

It seems the problem is caused by commit https://github.com/torvalds/linux/commi ... 27b81bddf7. Mainline kernels before this commit perform the scrub successfully; starting with this commit btrfs scrub fails.

I've also noticed that on mainline kernels I often get messages like this during the scrub:

Code: Select all

[   47.532829] xhci-hcd xhci-hcd.3.auto: ERROR unknown event type 37
From some googling it seems that this is caused by too slow handling of XHCI events.

EDIT: I have irqbalance enabled; I'm wondering if that might be causing problems like this.
EDIT2: Crash occurs even with irqbalance uninstalled.
EDIT3: Interestingly, I don't see the "ERROR unknown event type 37" messages under Hardkernel 4.14 kernel at all. However, I've seen them under mainline 4.14.
EDIT4: The JMS578 USB-SATA bridge is currently running firmware v173.1.0.2.

I think that the "unknown event" error and the crash might not be related. I've cherry-picked the problematic commit on top of the odroidxu4-4.14.y branch and I got the crash there too.

Re: USB controller dying under heavy IO load

Early on when I moved from 3.10 to 4.9 there were instabilities with regard to attached storage that could be mitigated by reducing the queue length for the device. Something like:

Code: Select all

echo 100 > /sys/class/block/sda/queue/max_sectors_kb
You could try it before doing intensive IO operations.

I've been running 5.4.3 on my cloudshell 2 for well over a year and have no issues, current uptime is 83 days.

The branch is from Hardkernel git.

Looking at the modules modified date it seems to be from January 6, 2020

Thank you for your replies. I've now tried decreasing the maximum queue length, but unfortunately the crash persists.

However, I have partially solved the problem that led me to wanting to move to kernel 5.4. I've managed to (locally, not in the Hardkernel git) merge the latest mainline stable 4.14 into the Hardkernel XU4 tree and the resulting build is running stable so far; so hopefully the kernel has the necessary security patches for now.
