Description Bojan Smojver 2003-08-04 02:08:54 UTC 
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686) Gecko/20030530 Galeon/1.3.7

Description of problem:
The machine is ALR Revolution Quad 6, 4 x Pentium Pro 200 MHz, 256 MB ECC EDO
RAM, 2 x Mylex DAC960 RAID controllers, multiple Digial RAID boxes, DLT tape
drive (DEC TZ88), 2 x DAT tape (Sony SDT-5000), 2 x Intel EtherExpress PRO 100B
(bonding configuration), 2 x Symbios logic SCSI controller (8-bit).

I was running a backup (tar) on this machine to the DLT tape drive when this
error occured.

This is what I found in /var/log/messages of this system:

On the same SMP box, there seems to be other problems with 2.4.20-19.9smp
kernel. Here is what I found in the log this morning:

----------------------------------------------

The machine kind of runs after this, but if I attempt to do "ps ax", grep
through /proc or something similar, the process I started cannot be aborted. In
essence, I have to reboot the machine to make it good again.
