Hi all,
Only recently I upgrade my Dell 5470 to Kernel 5.11.1 without any problems.
With the upgrade to 5.11.2 the system refuses to boot. -> KERNEL PANIC
Reverting to 5.11.1 didn't change anything. Neither does the update to 5.11.4., today.
Installing the LTS Kernel (5.11.21) make the system booting again, BUT strangely the internal Dell microphone is no longer detected. It used to work flawlessly with 5.10.16 a couple of days ago.
A Ubuntu live system I just booted found the microphone and it works ...
I unfortunately have only little knowledge on how to debug kernel related stuff. Could please someone advise, where to begin.
Btw. the pacman update to 5.11.4 on my two desktop PCs ran without probs. All connected MICs are working just fine!
Any help is greatly appreciated!
Supplement: archlinux-2021.03.01-x86_64.iso refuses to boot either ...

I can't update to 5.11.x as well.
Edit: oh, just re-read and you can boot 5.11.1 apparently. I couldn't /
Lenovo Yoga C740-15IML
Intel(R) Core(TM) i7-10510U CPU @ 1.80GHz
With linux-lts I can boot up nicely.
With 5.11.4 I get:

I'm currently trying to capture a video with my mobile. Quite challenging with a glossy display ...

Out of curiosity, does you MIC still work? I don't get it working again even if down grading to Kernel 5.8.14.
Cheers.
That (hopefully) was only a random coincidence ... I could fix this one by (re)choosing the correct profile for the "built-in-audio" in pavucontrol.

+1 here with a Dell Precision 7510.
It's hard to tell what's printed on screen, but I caught a "general protection fault" in the stack trace.
I'll try the LTS kernel to see if it's better.

My Dell Latitude e5470 is affected too. I use the 5.10 linux-lts kernel for now.
The archlinux-2021.03.01-x86_64.iso does not boot either.

It might be the bug with dell_wmi_sysman https://bugzilla.kernel.org/show_bug.cgi?id=211895 patches for this are currently on review, and it was recommended that till they get into stable maintainers would apply the patches themselves. Gotta wait for that.

FWIW, patches are in 5.11.11 that is in the repo now. So worth re-testing with 5.11.11.
