Public bug reported:
Happened on Lenovo T14 AMD gen 2 5850U running Mantic 6.5.0-13-generic
Under load, GPU crashed resulting in a weird behavior. Screen froze,
blinked a few times and the laptop suspended. After wakeup a normal
login screen showed up but after logging in, it crashed to black screen
with a message: " cp queue preemption timeout". Eventually I was able to
log in to a clean session.
