FYI, the test_arm_bpim2u_gmac test just failed during one of my CI runs:
https://gitlab.com/thuth/qemu/-/jobs/4565108610#L300
Looking at the debug.log in the artifacts, it looks like the kernel was
hanging during boot:
10:53:56 DEBUG| of_cfs_init
10:53:56 DEBUG| of_cfs_init: OK
10:53:56 DEBUG| ALSA device list:
10:53:56 DEBUG| No soundcards found.

10:54:26 DEBUG| vcc5v0: disabling
10:55:15 ERROR|
...
10:55:15 ERROR| RuntimeError: Test interrupted by SIGTERM
I can reproduce the problem locally on my laptop when running the test
repeatedly, e.g. with:
make check-venv
for ((x=0;x<10;x++)); do \
./tests/venv/bin/avocado run \
tests/avocado/boot_linux_console.py:test_arm_bpim2u_gmac ; \
done
1 out of 10 runs were failing.
Any ideas what could be wrong in those failing cases?
