2.4.20 - it's a heavily patched one, tho (out of gentoo's portage).  
should i try a vanilla kernel?

hmm...  well, rc7 has locked for me very shortly after system startup, 
top reports plenty (>200mb) free, so this shouldn't be a free resource 
issue.  it seems to only occur if i try to rapidly open and close the 
device (when i say 'rapidly' i mean about once per second for about 
10-25 seconds).

it's sub-ideal, but i'm using esd for now (with a really high timeout 
for releasing the pcm device) to avoid the excessive reopening behaviour.

thanks for your help - please let me know of any other ways i can try to 
gather information.
