Urgent help for panicing E420
2007-12-24 20:16:00
Bit of an urgent problem, hope you can help.
An E420R keeps panicing. It will only stay up for a few minutes in single
user mode, seems like less in multi user mode.
Im suspecting either fs corruption on / or /var or faulty disks for these
partitions. The system uses disksuite and has mirrored internal disks for
filesystems /, /var and /opt. The external disks are configured as a raid5
but these are not my concern at the moment - Ill fsck them once I have a
stable single user system. Some more presise info:

When the system panics it looks like this (lines have been wrapped) :

I did a boot from CD and the system behaved itself. Im off to try and do a
ufsdump.
I have the luxury of a spare (new) E420 and spare (new) drives. Im trying
to figure the fastest and saftest way to have a working system for the
users tomorrow.
I want to know if Im dealing with dying disks, filesystem corruption in /
or /var, dying HD controller or something else. Any other useful advise is,
ofcourse, very welcome.
TIA
