Sorry for not noticing earlier (I think the test is not run on gitlab-CI), 
but I just noticed another failing avocado test:

tests/venv/bin/avocado --show console run \
 tests/avocado/tuxrun_baselines.py:TuxRunBaselineTest.test_x86_64

... seems to hang now (and finally gets "INTERRUPTED").

If I got that right, the test is basically more or less doing:

 wget https://storage.tuxboot.com/x86_64/bzImage
 wget https://storage.tuxboot.com/x86_64/rootfs.ext4.zst
 unzstd rootfs.ext4.zst
 qemu-system-x86_64 -cpu Nehalem -M q35 -kernel bzImage \
  -hda rootfs.ext4 -m 2G -append "root=/dev/sda console=ttyS0" \
  -serial stdio

Then log in as "root" and shut down with "halt".

The "halt" works fine with git master, but it fails for me when I have your 
patches applied. Could you please have a look?

 Thanks,
  Thomas
