Dear Maintainer,

While I was running ffmpeg to do a screencast showing the capabilities of
gsequencer. But while doing so the GPU crashed after some time of playback.

The system was not usable, anymore. I wasn't able to switch to TTY. Only
mouse pointer was still responsive.

I configured my display to run at a lower resolution 1920x1080x60 instead of
the available 3840x2160x30.

Here is my ffmpeg command used:

`ffmpeg -video_size 1920x1080 -framerate 30 -f x11grab -i :0.0 -c:v libx264rgb -crf 0 -preset ultrafast ags-screencast-001.mkv`

Here is my $HOME/.gsequencer/ags.conf:

[generic]
disable-feature=experimental
autosave-thread=false
segmentation=4/4
engine-mode=deterministic
rt-safe=false
gui-scale=1.0

[soundcard-0]
backend=alsa
capability=playback
buffer-size=1024
pcm-channels=2
format=16
samplerate=44100
device=hw:CARD=PCH,DEV=0

[recall]
auto-sense=false

[thread]
model=multi-threaded
lock-global=ags-thread
lock-parent=ags-recycling-thread
thread-pool-max-unused-threads=4
max-precision=125

I have recorded the screen using my phone:

Since, I have got some functional integration tests for `gsequencer`, there
was the idea about to bisect the upgrade that introduced it.

But first, I try to use an ordinary FullHD monitor and check if the problem
happens with it, too.

Hello Joël,
I guess I have a similar setup and had similar
lock-ups as your video shows.

I had opened this upstream bug [1].

Either with latest bios updates the situation improved,
or last year I started to do after each cold boot another
warm boot and have the feeling that way this issue does
occur a lot less to not at all.

Could you still reproduce this issue - and does it show
after a reboot too?

Kind regards,
Bernhard

Hello.

Like part of #987388, I had the same problem just now (gpu reset). The driver crashed when I pressed the record button in OBS studio with VAAPI.
I got a black screen and then back to the desktop, with a still image of my last action, everything was frozen.
I didn't lose the tty, I was able to restart lightdm without rebooting the machine by changing the tty and kept the uptime.

You will find the log attached.

Package: xserver-xorg-video-amdgpu 19.1.0-2
xorg-server 2:1.20.11-1
Linux 5.10.0-7-amd64 #1 SMP Debian 5.10.40-1 (2021-05-28) x86_64 GNU/Linux

Thanks.
Max.
