When I start 4.4.110-rc1 on a virtual machine (qemu) init throws a

The VM host is a Haswell system.

The same kernel binary boots fine on a (other) Haswell system.

I tried:

4.4.110-rc1 broken
4.4.109 ok
4.9.75-rc1 ok

Does 4.15-rc6 also work ok?

Yes. Slightly different kernel config, but it boots.

All systems are OpenSuSE 42.3 64bit.

qemu is started only with:
qemu-system-x86_64 -m 2048 -enable-kvm -drive
file=tvsuse,format=raw,if=none,id=virtdisk0 -device
virtio-blk-pci,scsi=off,drive=virtdisk0

Am I the only one who sees this? Has anyone booted that kernel on qemu?

Any chance we can see the panic?

Attached a screenshot.
Is that useful? Are there some debug options I can add?
