Hello, I’d just like to report that I haven’t seen this problem in a while. The last time I see the “retry page fault” messages in my log was on August 9.
I’ve been using the ‘amdgpu/picasso*‘ files from linux-firmware commit c46b8c364b82 (“ice: update package file to 1.3.26.0”) so apparently this particular problem was recently fixed. Which isn’t to say that I’m having a trouble-free amdgpu experience, unfortunately. Every week or so my laptop comes back from sleep with the screen and keyboard frozen (I can still ssh into it), but now the error is: kernel: [drm:drm_atomic_helper_wait_for_flip_done [drm_kms_helper]] *ERROR* [CRTC:67:crtc-0] flip_done timed out But it seems to be a separate problem from the one reported in this particular launchpad issue. I’ll see if I can find a more appropriate launchpad issue and post the details there. Thank you all for your help and support with this issue. -- 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: Confirmed 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.
