Resend: Sorry copy and pasted a wrong mailadress for the xen-devel list.

Hi Boris / Juergen,

This morning i got this dom0 kernel crash (it occurred sporadically
before (during 4.11), but i didn't have serial console enabled at that
time so i had no stacktrace, only sporadic reboots).

It's running on an AMD phenom X6:
Kernel 4.11.0-rc7 with as latest commit:
94836ecf1e7378b64d37624fbb81fe48fbd4c772.
Xen-unstable with as latest commit:
94836ecf1e7378b64d37624fbb81fe48fbd4c772.

If you need more info please ask, testing will be difficult as i don't
have a clear testcase and
it can also run for days without trouble.

Sander
