Bug#565819: linux-image-2.6.26-2-xen-amd64: Periodic kernel panic freezes system involving xen and reiserfs
Package: linux-image-2.6.26-2-xen-amd64
Version: 2.6.26-19lenny2
Severity: important
I upgraded a Xen server with 3 domUs from etch to Lenny on December 22.
Prior to that date, the system had not crashed in 3 years on etch.
Following the upgrade the server performed properly until January 10, when
it crash with "Kernel panic: Aiee, killing interrupt handler!"
Subsequent crash on January 18 makes me think there's something rotten
in the newer kernel. I suspect it's traffic-related as well.
Don't know how to capture the full trace from the console as I can only report
what was on the screen (and then only copied it by hand). If there's
a better way to capture this information, please let me know. I want to help
solve the underlying issue, but I also need this server to run reliably.
I'm considering using a 2.6.18 series kernel or buying a new machine.
Any advice on that?
System reboots normally, although I see some reiserfs journal replay in the
logs and the soft raids need to resync.
