System: NetBSD vash.cel.plethora.net 3.99.19 NetBSD 3.99.19 (VASH) #0: Wed May 10 22:58:54 CDT 2006 seebs@vash.cel.plethora.net:/sys/arch/i386/compile/VASH i386
Architecture: i386
Machine: i386
>Description:
	The auich driver, which used to work just fine, now crashes
	consistently on my system.

	1.  If the system sleeps and comes back, it panics immediately.
	2.  If simply used regularly, say for playing a series of mp3 files,
	it eventually fails, leaving the kernel in a state which quickly
	leads to panics.  It may be possible to run for a while getting
	errors like "unable to create pipe" for nearly any command run.
>How-To-Repeat:
	mpg123 *.mp3
>Fix:
	Not known.  This driver was working fine on my system maybe two or
	three months ago.  dmesg output attached; relevantly, this is an ICH3.

	If I had to pick a patch to blame this on, it'd be the 1.102 patch,
	but I can't easily isolate it.
