Hello,
when running qemu with GPU passthrough it crashes with 5.6 and also
5.7-rc kernels, it works with 5.5 and lower.
Without GPU passthrough I don't see this crash.
With bisecting, I found commit that causes this BUG.
It seems bad commit is f458d039db7e8518041db4169d657407e3217008, if I
revert this patch it works.

commit 5a605d65a71583195f64d42f39a29c771e2c763a

kvm: ioapic: Introduce arch-specific check for lazy update EOI mechanism
commit f458d039db7e ("kvm: ioapic: Lazy update IOAPIC EOI") introduces
a regression on Intel VMX APICv since it always force IOAPIC lazy update
EOI mechanism when APICv is activated, which is needed to support AMD
SVM AVIC.
Fixes by introducing struct kvm_arch.use_lazy_eoi variable to specify
whether the architecture needs lazy update EOI support.
Fixes: f458d039db7e ("kvm: ioapic: Lazy update IOAPIC EOI")

Yes, this this patch works, there is no longer kernel BUG.

Boris,
Would you mind sharing your QEMU command line and how to set up the VM?
I would like to double check to confirm that this is not specific to
running on Intel system.
Thanks,
Suravee

This is minimal example.
When windows starts loading after cca 3 seconds crash happens 100% of
the time.
This also happens with Linux guests and also sometimes in TianoCore
Settings/BIOS or whatever it is.
Also if I'm in TianoCore settings and I write "quit" in qemu monitor
there is always crash.

Hello,
when running qemu with GPU passthrough it crashes with 5.6 and also
5.7-rc kernels, it works with 5.5 and lower.
Without GPU passthrough I don't see this crash.
With bisecting, I found commit that causes this BUG.
It seems bad commit is f458d039db7e8518041db4169d657407e3217008, if I
revert this patch it works.
