Kernelbug / panic with 5.9.11

[mbod]

Hi,
today I just realized that during shutdown the console is throwing a kernel panic. This is at the very end of the shutdown process and it scrolls on the screen pretty fast. There is no trace of it in the journal therefore I can not tell when that issue occurred for the first time. It does not happen with LTS kernel 5.4.

I captured a video of the shutdown screen and extracted two screenshots from it:

Picture 1:

Picture 2:

Any idea what is causing this?

Kernel 5.9 - kernel panic on shutdown

Anyone else experiencing kernel panic on shutdown? The problem was introduced with this commit, and has been reported on LKML. A fix is now available and you can find it here. Should appear in stable and 5.10 soon.

Yep

Hey @mbod,

there is a new thread opened with the same problem as it seems: Kernel 5.9 - kernel panic on shutdown have a look there, maybe your and their thread can be merged?

[mbod]

Yes, that looks very familiar.

It’s 5.9.11-arch1-1 - you should use 5.9.11-arch2-1. No problems here.

I can confirm that the new arch2 package from arch testing solves the issue!
@axt: Thanks for pointing me there.
