Can you please try v6.1?
It's reproducible in v6.1.9. I finally can reliably reproduce it, it only happens when I start a VM with qemu.
Specifically adding this device to the qemu instance:
<hostdev mode="subsystem" type="pci" managed="yes"> <source> <address domain="0x0000" bus="0x00" slot="0x02" function="0x0"/> </source> <address type="pci" domain="0x0000" bus="0x04" slot="0x00" function="0x0"/> </hostdev>
And that slot is used by this hardware:
0000:00:02:0 Intel Corporation TigerLake-LP GT2 [Iris Xe Graphics]
Removing it from the qemu instance solves the issue. But it's still a kernel bug anyway.
Please file a bug at fdo gitlab:
