After 4 days of stability I just had the retry page fault problem again,
with stock linux-firmware 1.197 and kernel 5.11.0-17-generic.

So apparently the flatpak update made the problem less likely to happen,
but it still does.

Life got in the way and I wasn't able to do this yet.
With it taking 4 days to reproduce the problem with the current stack, I
think it still makes sense to revert the flatpak update.
Unfortunately "flatpak history" seems to be broken on my system:
$ flatpak history
error: appstream2/x86_64 is not application or runtime
I'll try using ostree directly. I don't think I'll be able to do it today,
but hopefuly within the next couple of days.

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:

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.
