i810_audio.c v0.11 kernel lockup

[Ulrich Leodolter]

problem:	kernel lockup when apps tries to play sound
kernel:		linux-2.4.17-pre8
i810_audio.c:	version 0.11 from 
http://people.redhat.com/dledford/i810_audio.c.gz
processor:	Intel Pentium4 1.5GHz
mainboard:	Luck Star P4A845S (http://www.lucky-star.com.tw)

i have compiled the driver with all DEBUG enabled,
here are the last kernel messages before the kernel dies:

The 0.11 version had a known lockup issue.  The current driver on my web 
site is 0.12 (and has been since very shortly after I announced the 0.11 
version I think).  Anyway, please retry with that driver and see if things work.
