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. -- Jens Axboe
