Hey, this is my same motherboard chipset. It' s dma buggy! Try to run a
soundblaster with digital audio at 44100 stereo on 2.1.8x with high disk
activities and tell me if it will lock your machine please (your poweroff
button should became disabled after the lock). I have a patch to fix it. I
also found that running hdparm -W1 lock the hd, but then the timeout
resets ide0 and all return to work again, so I don' t use -W1 now ;-).
