There is something wrong with your storage. But I can't see the whole error

I unplugged it and plugged it back in and it restarted seemingly without issue.

I'm going to restore the card(will try other cards as well) back to the state it was in before the upgrade, and try again with a serial console attached.

Yeah observe it if it's a bug it seems like a rare one.

I have exactly the same on my odroid C2.
Upgrading from 8.90.2 to 8.90.3.

Only thing thas was possible was flashing 8.90.3 on emmc then restore backup.
After that netflix is crashing soon as i open netflix.
Then i rebooted THE system and after that THE same issue on boot screen again.
Installed 8.90.2 and everyyhing is running fine.

I think something is really wrong with this build on odroid C2.

@ raybuntu did you test this on your odroid c2??

It keeps doing it, somewhat randomly.

I've not taken a close look at it yet but here is what I get from the serial console https://pastebin.com/qDF66zZa

Also unrelated I found that if you try to play a game and then try to watch any video, it will tell you it can't find the emulator.

Has anyone else noticed that their C2 runs a lot hotter when using 8.90.3 compared to previous releases?

I've gone from about 48c at idle to 70c at idle. This is on two different C2.

It looks like kodi might be part of the cause since it is sitting around 50% cpu usage now when on previous version it was at around 16% when doing nothing with the screen off.

Try disabling the screen saver.

Doesn't make a difference.

I have two identically configured C2 both fresh installs of 8.90.3 with largish libraries, about a foot apart. One screensaver set to dim(same as I had on 8.90.0) one with screen saver turned off. Both are at 70c right now. Both show about the same usage. I don't know the room temp, but I have a third C2 running it's original 8.90.0 about a foot over from the two that are running the newer version that is at 46c.

Kodi using that much CPU is a big part of the issue, question is why is it doing that.

Have you tried a fresh install, no add-ons? Narrow it down a bit further.

Is the governor set to performance or ondemand?

In the process of prepping new cards right now.

Plan is fresh install, with nothing more then setup wizard run.
Then walk through the setup step by step with a 30 minute break between steps, until I get a spike.

However, add-on wise everything comes from the default repos, and it's pretty much youtube, vimeo, yahoo weather, and studio icons.
So nothing crazy there.

*edit*

governor is set ondemand

*edit*

I pretty much leave CoreELEC as it comes. So have not gone changing much, it's local database, no advanced settings or anything under the hood modified.
Normally I have one C2 running it, mostly just as a way to see what is happening with other peoples builds, and as a reference to my own builds.

Fresh install, no configuration, no library, and it's 66c.

Part way through testing, I realized the cause might have been staring me in the face on the release notes page this whole time. They changed the default for algorithmdirtyregions, and it took my brain multiple days and multiple readings to clue in that dirtyregions under fixes in the release notes meant the dirty-region processing algorithm for the gui and not something to do with dvd/blueray/etc.. region encoding.

change the setting, and temps back to normal.

and, I think I'm done with technology for the day, since my brain is clearly not up to it right now.

Dirty regions strikes again. Glad you got it resolved.

Is it possible/advisable to overclock the C2 CPU with 8.90.3? I tried changing
setenv max_freq "1536"

to

setenv max_freq "1752"

but the max cpu frequency didn't change after rebooting

while updating CoreElec to new version, Is there a way to prevent partition renaming?

I have an emmc with Android, ubuntu and CoreElec.
Everytime I update CoreElec it breaks it all due to partition renaming it does.

Thank you.

Hey.

The temp problem and CPU usage in 'CoreELEC' is about dirtyregions. And the Netflix should be updated to a newer version, the it will run normal.
dirtyregions. ( You can change algorithmdirtyregions in /storage/.kodi/userdata/advancedsettings.xml value to 3 )
