Also, this might be unrelated, but the following happened around this patch (ie https://github.com/torvalds/linux/commit/0c5c62ddf88c34bc83b66e4ac9beb2bb0e1887d4) I sometimes run Win11 under qemu/kvm/vfio (gfx card), and it stopped booting (even with the latest patch for pci). 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.
