Package: 2.6.32-5-xen-amd64
Severity: important

Since a couple of days ago on high loads a domU is constantly 
rebooting itself after a kernel panic. Below you can find the 
console logs. If there's anything else I can provide let me now.

Version: 3.4.1-1~experimental.1+rm

Debian 6.0 Long Term Support has ended, and the 'linux-2.6' source
package will no longer be updated.  This bug was reassigned to the
'linux' source package earlier today, but I am now closing it on the
assumption that it does not affect the kernel versions in newer Debian
releases.

If you can still reproduce this bug in a newer release, please reopen
the bug report and reassign it to 'src:linux' and the affected version
of the package.  You can find the package version for the running
kernel by running:

    uname -v

or the versions of all installed kernel packages by running:

    dpkg -l 'linux-image-[34]*' | grep ^.i

and looking at the third column.

I apologise that we weren't able to provide a specific resolution for
this bug.

Ben.
