--- Comment #28 from nmr  ---
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 #1 SMP Debian 4.19.16-1
(2019-01-17) x86_64 GNU/Linux

I'll report back when I upgrade to 4.20

The GPU hang is most likely caused by a bug in mesa.  What kernel are you
using?  GPU reset was only recently enabled by default on certain asics.  Even
if a GPU reset is successful, user mode programs (like X or the wayland desktop
compositor) need to properly catch and handle GPU resets which they don't
currently today.  Can you try 4.20 or newer?

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.

--- Comment #20 from Axel Davy  ---
It looks like from the previous comments the problem is in radeonsi.

As a 'temporary fix', you could try this patch:
https://github.com/iXit/Mesa-3D/commit/976f3fe791b0aa34cc04eaac53147eb60089e0f7

This patch recompiles the shaders with the boolean and integer constant values
given by the app, thus the branches controlled by them are simplified.

UMR dump for similar dxvk hang

I see that there is only one wave noted in the dump, and the shader appears to
be of reasonable length.

>   pgm[7@0x800100025000 + 0x94  ] = 0x3727c5ac  ;; 
>  

Are these timed NOPs or something to achieve the correct cycle delay to avoid
load hazards or something?

dmesg during reboot/recovery

On the basis that it may be shader induced I repro'd a similar hang with dxvk
(v0.95-5-gcc38412). 

FWIW here's dmesg during subsequent GPU recovery (which fails :( ) and reboot
(which hangs.) It appears hung on a DMA, and/or hung doing a modeset, acquiring
the modeset lock.

Pretty much. The shader is stuck and doesn't continue. Also the shader is
insanely huge with lots of SGPR spilling and branching.

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

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

Haven't looked at the ring buffers, is there some kind of deadlock in there?

We can try and check the gfx command buffer for latest commands and CUs status
- 

Clone and build our open source register analyzer from here -
https://cgit.freedesktop.org/amd/umr/

After hang happens please get following outputs -

sudo umr -lb > umr_dump
sudo umr -O verbose,use_colour -R gfx[.] >> umr_dump
sudo umr -O halt_waves,use_colour -wa >> umr_dump
dmesg > dmesg_dump

Yes, several times.

Yes, you request clean dmesg.

Now i attach dmesg output without pm-hibernate.

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#.
Today, when I went to a hung computer, I saw a new error in dmesg.
