I'm chasing a similiar bug since 2 weeks. The kernel crashed
with a double page fault and access to a very low address
(something like 0x00000098). I eliminated the RealTek card
(replaced by a 3Com) and things got better. But it kept crashing.
Now I have disabled SMP and things happen even more rarely (once
every 2 days instead of once every 3-4 hours). This is a very fast
machine (733) potentially with chipsets not supported too well.
I have a few crash dumps I could people have a look at, at least
send the output of kdgb.
If anyone is interested, I may be able to provide access to
the machine and the crash dumps (you can't ftp them, they
are 1GB+ in size, it would cost me NZ$250).
