I'm seeing this on Debian 12 without Wayland or Xorg simply by running
#!/bin/bash
chvt 3
for j in $(seq 80); do
echo "$(date) starting round $j"
if [ "$(journalctl --boot | grep "failed to allocate VRAM BO")" != "" ];
then
echo "bug was reproduced after $j tries"
exit 1
fi
for i in $(seq 100); do
dmesg > /dev/tty3
done
done
echo "bug could not be reproduced"
exit 0
This allowed me to run git bisect which identified the following commit:

drm/qxl: simplify qxl_fence_wait
Now that we have the new release_event wait queue we can just
use that in qxl_fence_wait() and simplify the code a lot.
