Spontaneous reboots with Dell PowerEdge

Fri Jul 7 10:52:17 UTC 2006

Hi,

I am hoping that someone has come across this weird happening with Dell PowerEdge
1800.

We have one such server, with dual power supply, running FreeBSD 4.11-STABLE.

Spontaneously, the server does a hard boot and comes back up. /var/log/messages
only states the previous system shutdown was unexpected. This happens at random
times and is completely unpredictable. We have replaced all the RAM modules
with a completely different set, just to eliminate anything to do with faulty
modules, but this has not cured the problem.

The server has 7 disks on a RAID 5 set. A hard reboot definately calls for a
fsck, which makes the reboot process take forever. I have fsck_y_enable in
rc.conf, because otherwise someone will have to manually run fsck after these
spontaneous reboots!

I am considering a serial console option to see if I can capture 
something, but apart from that I am at my wit's end reagrding this issue.

Here is the output of dmesg.boot:
