Subject: Re: [PATCH 4.4 00/37] 4.4.110-stable review


When I start 4.4.110-rc1 on a virtual machine (qemu) init throws a
segfault and the kernel panics (attempted to kill init).
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?

Confused,

   Thomas
