Works fine for me on current master, boots and run self tests and
then shuts down. Tried it 5 times now.

axboe@r7625 ~/g/linux-vm (master)> qemu-system-i386 --version
QEMU emulator version 8.2.4 (Debian 1:8.2.4+ds-1)
Copyright (c) 2003-2023 Fabrice Bellard and the QEMU Project developers

Then tried 6.11-rc1 10 times in a loop, and also didn't see any failures.

I then switched to using gcc-11 as that seems to be what you are using,
and them it does indeed bomb during boot. Funky. I'll check the post
branch and see if it's anything from there.
