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: commit 5a838e5d5825c85556011478abde708251cc0776 (refs/bisect/bad) Author: Gerd Hoffmann <kra...@redhat.com> Date: Thu Feb 4 15:57:10 2021 +0100 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.
