SubjectProblem with machines rebooting
Hi all, I'm having a problem with a machine that's freezing up every few 
days. It was running the standard RedHat kernel 2.2.5-15, and has since
been upgraded to 2.2.11 in order to try and fix this problem. Here's what I
think is some helpful output from /var/log/messages:

The error about the floppy drive is what's on the console when I reboot the
machine. These are Rackmount clones that run AMIBios if I recall. I can
verify that if it's relevant. They're dual-processor Pentium II
motherboards, I'm not sure which brand. I have a check in to our vendor to
get that info. Strangely, we have lots of machines out in the field and
don't have this problem, however, a lot of them are RH 5.2, so I hope this
isn't either a RH version issue, or a kernel issue. Anyway, any direction
or help is very much appreciated. Here's our dmesg output for this machine
in case that helps:

And no, there's nothing in the floppy drive. I don't think we've ever
actually used it...
