It's been a while, but I believe it dies during APIC detection... it's real
early on. As far as I can tell, no kernel previous to 2.1.108 would boot on
this machine, however I only tried a few when I got it (2.1.106, 2.0.33,

2.0.x works fine in non-SMP however. My other machines (Supermicro P120
boards) crash all the time, no particular reason.. no oops, just straight
hang or an oops scrolling so fast that I can't copy it down even if I want
to with 2.0.x. Heck, the 3c59x card in one of the boxes locks up all the
time (ifconfig eth0 down/up fixes, but breaks gated so I have to restart

I don't think I've ever gotten a usable oops written to disk... I just wish
I could insert a disk into the drive and have it write the oops to it on a
crash.. would make my life easier :)

I must have really bad luck since one of the Supermicro's was up for 8
months straight, and now I'm lucky if it goes 8 days.
