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

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?

I've now released 4.4.110, which had 4 more patches on top of what
4.4.109-rc1 had in it, that should hopefully resolve these issues.

Can you test that and let me know if you still have problems?

It's fixed. I can boot 4.4.110 on qemu without problems so far.

./test_vsyscall_64 still fails though, like Kees wrote about 4.4.110-rc1
https://lkml.org/lkml/2018/1/5/123

That's another issue?


Thank you very much.
