All boots with efi32 bios crash. This seems to affect all stable release
candidates; so far I have seen it with v5.10.130-132-g6729599d99f and with
v5.18.11-62-g18f94637a014. Test results from mainline and from v5.15.54-rc1
are still pending.

With rc2 the perf build issues got fixed.

but we still see
Kernel panic on x86 while running kvm-unit-tests.
