Hi all,

I've seen few kernel panics,

I'm using RHEL kernel 2.6.18 + patch-53.1.19.el5.028stab053.14-combined
config is kernel-2.6.18-i686-ent.config.ovz

Only little difference w/ other setup : i'm using drbd for data storage.

I didn't found yet a way to reproduce this problem on-demand.
So far the problem is only seen in syslog/kernel messages, system is
still running correctly (or looks like).
