I've never touched a computer that had a SIG11 problem, I run probably 100
linux boxes machines at math and probably 40 ish at ITD.  

I believe the GCC faq basically says:

Q: #N Why does gcc keep dying with a SIG 11 in different places.
A: Bad memory

I'd first buy some quality memory, i.e. www.crucial.com, or at least
name brand.  Don't overclock, buy an ASUS motherboard, or at least
a name brand (abit, tyan, supermicro and similar)

Most anything should work.  I'd recommend a athlon for price/performance
is a priority (and absolute perf for that matter).  Kt266a is a very nice
chipset, great memory system, I've heard of no complaints, I have a few
around, at least one asus, and 1 gigabyte.  The gigabyte is somewhat
unique in that it has onboard linux compatible network.

I just (today) got a microatx nvidia abit motherboard.  Network, ethernet,
and awesome (for onboard) 2d/3d, about gf2mx speed.  Just add dimms,
cpu, and fan and your off and running.

I've had I think zero returns on www.crucial.com, I'd definitely get
PC2100 memory, do NOT get a motherboard that takes 2 types of memory.

Mixing brands isn't recommended, I'd pull one and see if the problem
persists, if it does switch.  I'm betting either one is defective
or both.

It's where I'd look first.
