The screen displays kernel panic, I can't able to get the system log from the LTS kernel, it doesn't show up. I am on linux-lts 5.10.X now I have fear of upgrading any further.
I attached the photos of the kernel panic screen and I attached my system information. I included the packages list also in case of need.

I had a problem with this kernel too. My nvme became "read-only" once after a forced reboot and gnome-shell keeps on crashing. Moving to 5.10 LTS until this bug is fixed.

Downgrading the kernel to its version 5.11.7 fixed all the crashes I had. Linux 5.11.8 is broken on my installation with IOMMU deactivated.

passing amd_iommu=off didn't solve the problem. Same error occurs.LTS kernel works fine.

@venkatesh please test 5.11.8.arch1-1 which is currently in testing.

I don't have any machines with an AMD CPU so I'm not affected by this issue and can't test it. I just came across this bug report by accident whilst looking for possible reports/causes of another bug. :)

thanks guys, thanks @loqs the issue was gone after installing the kernel 5.11.8 that you given above. Now working fine. The issue was caused by amd_iommu but passing it kernel parameter doesn't help at all. now everything is working fine. Thanks all.

Please test that the issue is resolved in 5.11.9.arch1-1.

In some versions of 5.8.x can't able to boot without kernel panic, but later 5.9.x release fixed the issue now working fine.
