this may seem stupid, but I'd check the other CPU first.
you know that this cpu works, okay, try booting with just the
other cpu. put it in the smae socket as this one, and then
reboot the same kernel. If it dies, it is the cpu ...

it may not have been that obvious, call the MB manufacturer

never used debian, on SMP.. but that should not be the
problem.. 2.0.36 I used for while and never had a single problem
with it .. what compiler are you using to compile 2.0.36? gcc
2.7.2 or egcs?

again swap CPUs to make sure both are good... also where did
it lock up with 2.2.9 ? was it also when doing fsck? what
message did it give you if any? how big is your hard drive?

looking at your ouput from dmesg it detected the memory
just fine...

it is not memory, I have those problems, on my system...

it is a SMP kernel I believe... and except for the fact that
it is detecting only one of your CPU's it looks just like
mine...
