Subject2.1.90/91 lock-ups -- RAID?
Date
I have two machines -- virtually identical hardware except for # of SCSI
disks. Main difference is the machine that is locking up runs RAID5 and
100BaseT (same 3c905 net card on both -- just 10BaseT on one machine and 100
on the other).

2.1.89 works fine (or at least hasn't crashed yet on either machine -- was
up for about 8 days before I upgraded to 90)
2.1.90/91 both lock up after a few hours of uptime on the RAID machine (the
other machine works fine on 90/91 as e-mail and web server). I tried to
"ckraid --fix /etc/raid5.conf" on the RAID box several times and each time
it caused the machine to lock-up (happened three times so it's pretty
repeatable).

Last lock-up at least happened quick enough (right after reboot while
running ckraid) that the console hadn't blanked yet...bad news is there
weren't any messages anywhere (console, messages, or syslog). SYSREQ also
didn't work and network didn't work (couldn't ping the box).

It looks like it's a RAID related problem to me as that is the main
difference between these two boxes (and since ckraid causes the lock-ups).
I've now re-booted to 2.1.89, run ckraid successfully (takes 35 minutes),
e2fsck, and all is well again...
