log trace obtained with crash

I finally managed to get crash running on a guest core file dumped by Xen.

I hope this log reveals a bit more of the cause.

Again, I triggered the panic by simply copying a large file from one guest to
the panicking guest with scp. The guests have lvm backed disks.

Furthermore I made the following observations:

1. It is always the receiving guest (which is writing the file to disk) which
2. Dom0 does not panic when using it as destination;
3. A 12.2 guest on the openSUSE 12.3 VMM runs stable;
4. I am unable to crash the guest by local file copying;
5. In contrast to my previous report in comment 2, I was able to crash the
guest by not writing the file to disk, but to /dev/null.

If more information is required I am happy to provide, or do more specific
