Sounds good. > So at the end of the day (or earlier if I get a retry page fault) I'll do > the procedure you mention to use firmware 1.197 and only overwrite the > picasso* files to confirm if those are the ones that need to be changed. > > I don't know much about GPUs, but from looking at Wikipedia¹ I think my > model is a "Vega 10".

Based on that it will pick firmware files which begin with "picasso". It would be informative though to have the output from "lspci -vvnn" on your machine. Let's try the picasso files first. If that doesn't work you can try the vega10 files (without the new picasso files), then if that doesn't work, try both. Then we'll have an idea about what the minimal set of files is to fix the problem. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-firmware 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 linux-firmware package in Ubuntu: Incomplete 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. When this happens, I see this error in dmesg: [20061.061069] amdgpu 0000:03:00.0: amdgpu: [gfxhub0] retry page fault (src_id:0 ring:0 vmid:1 pasid:32769, for process Xorg pid 1141 thread Xorg:cs0 pid 1236) [20061.061103] amdgpu 0000:03:00.0: amdgpu: in page starting at address 0x800000401000 from client 27 [20061.061135] amdgpu 0000:03:00.0: amdgpu: VM_L2_PROTECTION_FAULT_STATUS:0x00101031 [20061.061147] amdgpu 0000:03:00.0: amdgpu: Faulty UTCL2 client ID: TCP (0x8) [20061.061157] amdgpu 0000:03:00.0: amdgpu: MORE_FAULTS: 0x1 [20061.061167] amdgpu 0000:03:00.0: amdgpu: WALKER_ERROR: 0x0 [20061.061174] amdgpu 0000:03:00.0: amdgpu: PERMISSION_FAULTS: 0x3 [20061.061183] amdgpu 0000:03:00.0: amdgpu: MAPPING_ERROR: 0x0 [20061.061189] amdgpu 0000:03:00.0: amdgpu: RW: 0x0 I'll attach a couple of full dmesgs that I collected. 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.
