I'm getting this irritating divide error on my 2.1.89 server every 4-24
hours. I finally actually wrote down the stack and call trace since they
never get logged, but ksymoops wouldn't work with my copy, and browsing
through /dev/ksyms manually only frustrated me more as only three or four
of the symbols in the Call Trace actually resolve. I'll append the kernel
config stuff and the oops, but basically:

An TX5N 430 TX Motherboard, by abit or asis or something...
Cyrix 6x86 MX 200
64 Megs RAM
Advansys SCSI Card
Colorado 5 gig tape (the reason for 2.1)

Nothing else really fancy, a mix of ide and scsi drives as well. It's a
linux only server that ran wonderfully with 2.0.33. I have ipv6 support
compiled into the kernel as I am trying to play with it, but it doesn't
seem to be the problem. That was my original though, but a kernel without
it (or rather with it as a module that wasn't loaded at the time) crashed
as well.

There doesn't seem to be a pattern to the crashes, the most recent one
occurred with no one logged in in the middle of the night.

If anything else is needed, let me know, also, I'm kind of clueless what
else to do about this, so if someone knows where to start to try to track
this problem down, let me know as well.

Here is the divide error, remember, I copied this by hand:
