So, I'm trying to get my file server back up and running since my old
hardware died. I know I've had plan 9 running on my desktop before,
and it's a little aged so I decided to upgrade to some new hardware
and convert the desktop to a file server. As it turns out, not that
simple. But at least now I feel a bit justified in being pedantic
enough to date my CDs:
2008/02/08 boots, livecd runs fine
2009/03/04 doesn't boot
2009/09/13 doesn't boot
09/13 gets as far as:

I think 03/04 got to the same point, but wasn't so verbose about it.
9atom boots fine so I think I owe Erik another beer :)
Just for completeness, the system is an oldish amd - nforce2
motherboard, SIL3112 SATA with a couple of 300g ST3300831AS disks.

take a look on segate's site for a firmware update for those drives.
i'm not saying that's your problem, but older AS drives (consumer)
have had firmware problems.
i'll just beat a dead horse here and repeat that it is very important
to choose a high-quality disk drive, and fewer platters leads to better
reliability. (fewer heads to crash.) here are the spec sheet numbers
i think are important
unrecoverable read errors < 1 in 1e15
mtbf > 750000 hrs (1% afr)
duty cycle 100%
unload cycles > 200000
mostly enterprise drives fit this definition.
