So the question is: why does the VM run stable on xen1 while it
crashes all the time on xen2. If I compare xen1 and xen2, only
real difference is mainboard (Supermicro X8 on xen1; Supermicro
X9 on xen2) and CPU (Xeon L5939 on xen1; E5-2609 on xen2)
As a next step I'll put the harddisks into another X8/Xeon L5639
server system and try to reproduce the crashes there. My bet is
that this system will not crash anymore. In other words, I guess
that this very bug is only triggered with the X9 + E-2609
combination.

Still the same question. Shall I send the bugreport to upstream?
Unfortunately nobody from Debian Linux kernel and/or Xen team seems
to care :-/

Sorry you haven't had a response from us so far. This seems to be
fairly clearly a Linux/Xen interaction and I don't know enough about
Xen
to suggest how to debug it.
As it involves a relatively old kernel version, I don't think Linux
upstream developers will want to hear about this unless you can also
reproduce it with a more recent version. Linux 3.16 is available (in
testing and wheezy-backports) if you would like to try that.
