Red Hat Bugzilla – Bug 33017
Dell Latitude LS500; nm256_audio = total freeze
Last modified: 2007-04-18 12:32:20 EDT
Dell Latitude LS500, rawhide-20010321, kernel-2.4.2-0.1.35,
Doing a "modprobe nm256_audio" freezes the system. Things investigated:
- Turn off all devices that can be turned off in BIOS.
- Set PnP OS to no (instead of yes).
- Load module in run level 1, without X (in case XFree86 was preventing
audio from getting memory - since its a multi-function chip).
- Try from cold boot to prevent warm reboot issues.
- Latest rawhide kernel used; sound has never worked on machine (in Linux,
unknown in Windoze since never used)
nm256_audio obviously works on some systems, e.g. on a Inspiron 3500.

Latest rawhide-20010407 (Apr 7th), kernel-2.4.2-0.1.51...
sndconfig detects card, machine still freezes when sndconfig tries to play sound.
No, nm256_audio does *not* work on a 3500, FWIW. :)
Do you get any warnings from the module, or does it just kill the system?
Are there any settings for the sound card in the BIOS?
Does the attached work for you?
