Hi,

works perfect besides the oops :)


That's not the plain 2.5.19, but the bitkeeper sources
(cset 1.594 of linux.bkbits.net/linux-2.5).

Hardware:

00:0f.0 Multimedia audio controller: Ensoniq ES1371 [AudioPCI-97] (rev 06)
	Subsystem: Ensoniq Creative Sound Blaster AudioPCI64V, AudioPCI128

Decoded oops from syslog:
