Bug#1054514: linux-image-6.1.0-13-amd64: Debian VM with qxl graphics freezes frequently
Package: src:linux
Version: 6.1.55-1
Severity: normal
Steps to reproduce:
1) Install Debian 12 as a virtual machine using virt-manager, choose qxl
graphics card. You only need basic installation without wayland or X.
2) Login from the console and save thë following to reproduce.bash:
#!/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
3) Run chmod a+x reproduce.bash
4) Run ./reproduce.bash and wait for up to 20 minutes.
Expected results:
4) The system prints a steady flow of text without kernel error messages
Actual messages:
4) At some point the text stops flowing and the script prints "bug was
reproduced". If you run "journalctl --boot" you see
kernel: [TTM] Buffer eviction failed
kernel: qxl 0000:00:02.0: object_init failed for (3149824, 0x00000001)
kernel: [drm:qxl_alloc_bo_reserved [qxl]] *ERROR* failed to allocate VRAM
BO
More info:
1) The bug does not occur if I downgrade the kernel to
linux-image-5.10.0-26-amd64_5.10.197-1_amd64.deb from Debian 11.
2) I used the following test_linux.bash to bisect this issue against
upstream source:
#!/bin/bash

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.
