Bug#861313: kernel BUG with kvm

["I. Schrey" <sy@schreyben.de>]

Greetings,

I'm having a similar issue on a kvm hypervisor running Debian Jessie.

It is running a vanilla kernel though, but it started hitting
a similar BUG today, after I upgraded from 3.12 to 3.16 series.

3.16.42 seems to be the first affected version.
3.16.41 is working without problems so far.


Also I can confirm that Debian kernel 3.16.39-1+deb8u2 works
and 3.16.43-1 does have the issue described.


I might try and git bisect the kernel, today or tomorrow,
unless someone else beats me to it.


Side note: the same 3.16.43 vanilla kernel has been working
fine on two Wheezy kvm hypervisors for more than a week now.



Regards
Ingmar
