This is very likely an unrelated issue to any kind of desktop hang
you're seeing. The graphics fuzz shaders are the result of fuzzing to
intentionally generate unusual control flow structures which are likely
to trigger shader compiler bugs. Typical desktop workloads don't have
such shaders, so any generic desktop hang you're seeing is almost
certainly unrelated.

Hi all,
Following the random crashes happenning with many users (e.g.
https://www.phoronix.com/scan.php?page=news_item&px=Raven-Ridge-March-Update),
not only on Linux but also Windows, I've been struggling to
reproduce and generate any error log.
After discovering that the error only happenned with KDE and games
(at least for me, see https://bugs.kde.org/show_bug.cgi?id=392378),
I could reproduce after a failing suspend.
The crash most of the times allows the mouse to keep moving, but
anything else works. Except for this time the keyboard worked so I
could switch the tty and save the dmesg messages. After this I had
to force reboot as it got stuck trying to kill the lightdm service
(gpu hanged?).
The errors are, see attached the full dmesg:
