[2.6.16-rc5][ALSA] ISA SB-AWE32 oops on sound init

From: Shawn Starr
Date: Mon Mar 06 2006 - 19:55:19 EST


I've finally taken the plunge (so to speak) and finally switched an old box
away from OSS, however, ALSA doesn't seem to work well with it ;-)

Whoever wants to depreciate OSS, please wait :)

Model below:

[17179579.964000] ALSA device list:
[17179579.964000] #0: Sound Blaster 16 at 0x220, irq 10, dma 1&5

Hope this stack dump is useful,

Shawn.
