I was finally able to spend a bit of time on this. Unfortunately, there’s not much to report back.

I don’t think I can narrow down which firmware file causes the problem, because I don’t have a last known good version. All firmware files that I tested (Ubuntu versions 1.190.5, 1.197 and latest linux-firmware.git) immediately trigger the bug when I try the only reliable reproducer I know (i.e., running flatpak’s com.github.quaternion package). Since it can take several days for the bug to happen if I just use the machine normally, it would take weeks to narrow down which of the picasso_* files is more stable relative to the others. And even then, I wouldn’t be sure about it. > > I think it may be related to a change in mesa. Specifically mesa > > commit > > 820dec3f7c7.

I’m running with the Mesa build from Mario’s PPA now. If I don’t see any issue within two weeks, I think it will be possible to say that the bug is gone, or at least much harder to hit. I can’t use my reproducer in this case, because I can’t change the Mesa version inside the flatpak image. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1928393 Title: linux-firmware 1.197 causes kernel to report error "amdgpu: [gfxhub0] retry page fault" Status in amd: New Status in linux-firmware package in Ubuntu: Incomplete Status in mesa package in Ubuntu: New Bug description: After upgrading linux-firmware from 1.190.5 to 1.197 (as part of the upgrade from Ubuntu 20.10 to 21.04), I started experiencing frequent and severe GPU instability.

Many of the times when this happens, the screen and keyboard freeze irreversibly (I tried waiting for more than 30 minutes, but it doesn't help). I can still log in via ssh though. When there's no freeze, I can continue using the computer normally, but the laptop fans keep running are always running and the battery depletes fast. There's probably something on a permanent loop either in the kernel or in the GPU. This bug happens several times a day, rendering the machine so unstable as to be almost unusable. It is a severe regression and I'm aghast that it passed AMD's Quality Assurance. After downgrading back to linux-firmware 1.190.5, the machine is back to the previous, mostly-reliable state. Which is to say, this bug is gone, I'm just left with the other amdgpu suspend bug I've learned to live with since I bought this computer. Please revert the amdgpu firmware in this package as soon as possible. This is unbearable.
