hi everyone,

We've made some changes on our ftp server, and since that it's been crashing
frequently (everyday) with a kernel panic.

We've configured the 5 IDE 160GB drives into md raid5 arrays with LVM on top
of that. All filesystems are reiserfs. The other change we made to the server
was changing from a patched 2.6.10-ac12 kernel into a newer 2.6.11.7.

Not being able to see the whole stacktrace on screen, we've started a
netconsole to investigate. Started the server and loaded it pretty bad with
rsyncs and such... until it crashed after just 20 minutes.

The netconsole log was surprising - "kernel BUG at kernel/sched.c:2634!"

Any help would be GREATLY appreciated.
