you're right. i misread the message i was thinking of. but i am sure
jaroslav said something about not understanding why a certain piece of
code was a problem with/without JACK.

all the evidence we have on jackit-dev points to this. people can
switch between ALSA versions, and it crashes with a newer copy and not
with an earlier one. there are some suggestions that its a kernel+ALSA
problem. the fact that it only happens in RT mode suggests some
interaction of SCHED_FIFO scheduling and kernel locking or something
like that.
