Package: linux-image-3.2.0-4-amd64
Version: 3.2.41-2+deb7u2
Hi,
Today I encountered a 'BUG: Bad page map in process <name>' in a wheezy
xen domU right after live migrating a couple of wheezy domUs between two
squeeze dom0s (lots of other domUs moved without a problem).
The vm still responds to icmp echo requests.
Output from xm console is attached to this bugreport in
xmconsole-badpage.txt
I made a dump from the domU by running xm dump-core <vm-name>
crash 6.1.6 from unstable seems to be able to read the dump
(6.0.6, in wheezy, complains with 'crash: cannot find mfn 0 (0x0) in
page index' and 'crash: cannot read/find pmd page', so that might be
related to
https://www.redhat.com/archives/crash-utility/2012-November/msg00025.html)
But, anyway, now I got this:
$ crash /usr/lib/debug/boot/vmlinux-3.2.0-4-amd64
2013-0605-2210.28-vm.39.core
crash 6.1.6

I'm happy to provide more information, but as I'm not an experienced
kernel dump debugger (yet ;]), I'll need some help from here onwards.
Exactly the same issue happened about a month ago while live migrating a
domU that was running linux-image-3.2.0-4-amd64 version 3.2.32-1 at that
time. Unfortunately, I did not dump-core it back then, but now I did.

both dom0s use xen-hypervisor-4.0-amd64 4.0.1-5.11, and are similar HP
