Yes, I'm. Dual P-Pro... I don't have any trouble with AudioPCI ES1370
soundcard.

Which kernel? I'm running still 2.0.36, but I can do some tests in 2.1.X
kernels, of course.. Did alsa configure script detect SMP kernel?

It is working, but probably in another way as you expect. This setup only
enables serious warnings, not verbose debugging of all lowlevel and
midlevel parts of ALSA driver. I'm using this switch in all cases and
I don't want see hundred messages for all I/O operations.

If you have trouble with crashes - try use alsa-driver/utils/insert script
(./insert audiopci). This script creates alsa-driver/snd.map file which
contains detail map of symbols for loaded ALSA driver. You can easy trace
in which code oops occurred.
