This problem I'm describing has nothing to do with the problems you are
experiencing [you're on an Alpha - an entirely different architecture] -
I'm sure there is a problem in the sound drivers that is causing the
lockups when playing sounds through the Soundblaster 2.0 16bit ISA card at
the same time as the IDE hardware being used - everything else in the
kernel works 100% reliably.
It's unfortunate this has cropped up at the end of my 2 weeks' vacation or
I'd have settled down to a long bug hunting session using printk()s :o(
Cheers,
Alex
