Yes, I compiled it myself using vanilla source.

I have since rebooted the machine and reinstalled the
very latest ALSA CVS drivers *without* applying your
patch, and everything is currently working. However, I
have currently got only about 30% of my 1GB RAM in
use:
$ free -t
total used free shared
buffers cached
Mem: 1033544 311820 721724 0
16340 156860
-/+ buffers/cache: 138620 894924
Swap: 498004 0 498004
Total: 1531548 311820 1219728
It is possible that the lock-up only occurs when the
RAM is so heavily used that Linux has difficulty
finding a DMA-able buffer. I know that the old
snd_pci_hack_alloc_consistent() function failed
gracefully in this case because I witnessed just such
a failure (and posted it to this list). So maybe my
box is doomed to lock-up again in a few days? I will
be extra vigilant!
