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.
