Package: linux-image-2.6.22-3-vserver-686
Version: 2.6.22-5
Severity: important
I recently had several kernel panics. Finally, I managed to get this
output via netconsole:

Kernel panic - not syncing: Fatal exception in interrupt
The timer-related functions in the stack trace reminded me of the fact
that I recently changed clocksource from tsc to hpet - this may explain
why I didn't get these panics before.
Looking for related changes in the vserver source revealed the
following:

(From http://linux-vserver.org/ChangeLog-2.2 )
It looks like the debian package contains the older version of this
patch, and the change may very well be the fix for the kernel panic
I observed.
So could you please consider including the updated patch in the debian
package?
