I get that it's triggered by Mesa, but don't you think it's a bug itself that
user-space can hang the kernel? I can't even switch virtual consoles when it
hangs.
I'm currently running Linux waldorf 4.19.0-2-amd64 #

The GPU hang is most likely caused by a bug in mesa. Wha

I'm getting the impression that AMD does not regard the kernel hang as the

Is it likely that this hang will get any traction with the AMDGPU team? Or
should I just close it and reset my expectations?

There may also be a bug in radeonsi, and thanks for the heads up, but every
circumstance where user code causes a kernel hang is a bug.

It looks like from the previous comments the problem is in radeonsi.
As a 'temporary fix', you could try this patch:

The wave dump suggests that image_sample_lz might be responsible for the hang,
but its SGPR inputs seem to contain valid descriptors.

Marek forgive my ignorance but why would SGPR spilling or branching cause the
hang? Is the shader just timing out somehow and the timeout resulting in a
kernel module abort?

There is some branching and SGPR spilling, so I guess that's the problem.

Did you do pm-hibernate before the hang happened ? I see a hibernate print just

In latest log i see no prints of hang.

What I mean by freezing.
The computer does not respond to the keyboard and mouse.
When I press 'Num Lock' or 'Caps Lock' the LED does not light up.
Clicking on Ctrl+Alt+F# does not switch to the TTY#.
