Another Linux distro boots fine under the same qemu/kvm/vfio, but Win11 stops at the boot screen. It worked well with 5.15.0 and a few PRs later - with the git tip it's not booting - and it works well with 5.15.0-rc7 Maybe related to pci/vfio changes, maybe not, just leaving it here for track record. I'll try to debug it a bit.
