Oops with 2.5.70-bk trying to load cs4236 module

[Art Haas (ahaas@airmail.net)]

Hi.

Here's the skinny on an oops I see when trying to load the cs4236 ALSA
module. My computer has a Turtle Beach Malibu sound card in it, and I
got it installed just before the PNP subsystem was rewritten in 2.5, so
I haven't had the card work yet. Getting it running has been on the
back-burner for a while. With the latest patches in from Al Viro I
thought I'd give it a shot and see if the kernel can load this module
up, but it can't.

Here's the dmesg output from my reboot into the 2.5.70-bk kernel pulled
from May 29. Just after bootin up I tried 'modprobe snd-card-0' and got
the oops.

The dmesg output does show that the card has some PNP conflicts
detected during the boot up. I have no idea how to fix this, and would
welcome some suggestions from some hardware-savvy people about how to
resolve these conflicts. Onward to the dmesg output and ksymoops
readout ...

resolve the PNP conflicts I see during the message. Any recommendations
on a forum or mailing list where hardware issues/gripes can be resolved?
