Hey Daniël Vos (vosdev),
thanks for the reproducer, it helps to ensure this fix is working as expected,

Similar configuration with Windows guests (6 total):

This is the first error, just after starting the first vm.

This issue occurs in my environment with a Windows guest even without

Same here, rollback to .35 and have a hold on that version until a fix
released. Behaviour aligns with comments on related thread - only when
passing through a PCIe GPU to a (linux in my case) guest. Drop the VM
back to QEMU graphics, serial terminal or other and this logspam does
not materialise.
I arrived at work this morning to find a frozen workstation with a full
disk. This bug was one of two relevant search results, so I'm
documenting the recovery steps I took here in case it will be helpful to
others:
1. Held down the power button until the PC turned off.
2. Waited a few seconds and
Ah yeah, that could be. I figured I'd test what's in -proposed but if
-proposed is a security only fix on top of -37, that wouldn't help much.
It's a bit frustrating because users would have gotten the busted kernel
as part of -37 which includes a security fix but then the only real
option to get
5.13.0-38.43 has the fix but 5.13.0-39.44 doesn't, presumably because
-39 includes urgent security fixes.
