Package: linux-image-2.6.26-1-xen-686 Version: 2.6.26-13 Severity: importang
Our Xen host experienced multiple crashed so we set up a remote system logger to get the call trace. The Xen hypervisor doesn't seem to log anything, though it might just be disabled.

Kernel panic - not syncing: Fatal exception in interrupt Previously, we also experienced some problems when polling SMART data from the hard drives, causing the dom0 to slow down any I/O which resulted in very high loads (>30 sometimes). After flashing the RAID controller, these problems seemed to be gone, though now this kernel panic happend. Not if the SMART problem is related, just mentioning here. Debian bug #504805 looks somehow similiar to our kernel crash, though the call stack slightly differs from this one. Unfortunately, I can't give any reliable information on the hardware, as the machine is down at the moment. As far as I remember, it is an old compaq server with 4x Intel Pentium III. I'll hand in more precise information as soon as the machine is back online. -- Leon Weber, l...@leonweber.de 0x8E04D7FC jabber: l...@jabber.ccc.de -- Wer Gründe anhört, kommt in Gefahr nachzugeben.
