nm256_audio.o

Hi
I've a problem with this module. For some reason it locks up my laptop
when modprobed. I'm running redhat's 2.4.7-10 on an i686 and i'm using
the neomagic 256 chipset which I believe is a graphics/sound combination
(with 4 meg or so of mem), the comp is a dell latitude ls.
The card does work, as it runs under the commercial oss drivers, thing
is because the machine locks tight running the kernel 256_audio, I can't
get any debug information, the machine has to be physically
unplugged/debatteried (lucky I run ext3 :) Not even a messages error. 
Anyone with any info? I'm gonna have a look and try to debug, but i'm no
kernel hacker.
Thks

A vague memory of when I used to use a neomagic-based laptop tells me that you
might want to try giving lilo (or whatever bootmanager you're using) a
parameter to limit your memory to 1MB less than your actual memory... although
this is from way back in 2.2.[789] days, I think. (For lilo, that would mean
typing mem=xxxM or adding append="mem=xxxM" to /etc/lilo.conf, where xxx is
your total RAM minus 1.)

Still not working, but thanks for the info anyway. Tried with 1,2 and a
couple of megs down from the physical memory from meminfo, but still no
dice. Afaik, i remember something about the memory of the graphics and
audio being shared, and since X cuts in first, it gobbles the memory up.
Not sure about that one as it still doesn't work if i run init3 and kill
X.

The Dell only works in 2.4.18pre7-ac3 or higher. Someone finally figured
out the problem and got me a fix. On other boxes its been fine for years

   The same (or related) thing happens with my Acer Travelmate 723TXV. Loading 
the module would lock the machine, but only if i had started Windows 98 before and 
warm booted the machine. After a cold boot, it would complain of a shared resource 
(?) problem, and quit. I have yet to check that fix you mention.
