Hi
we had one of our mail servers , going on kernel panic mode  ( not syncing
fatal exception) ... cause /var/queue/postfix was on reiserfs part .. it has
not been giving us any isssue quite some time , but yesterday and today it
went on Kernel panic mode , when we hashed out the reiserfs part it booted
properly .. we formated the part^ on ext3 later and things working fine now
. Could any one have a idea why this could have happened . The server hung
at 19:52:56 hours
Here is the logs
