Bug 18026

Jeff Garzik's native mode driver is in the newest mainstream kernels and that
should fix these problems.

If you ever do get that stuck again and don't have a bios option you can use
both the rescue disk technique or

linux init=/bin/sh

# mount -n -o remount,rw /
# vi file
# mount -n -o remount,ro /

reboot

(booting Linux to a shell with nothing else run)

PS: Bill - you might want to reassign this to kernel ?

if you turn on sound blaster emulation mode in the bios of this machine the
sound card will miraculously work and not lock the machine. The abit version of
this same board allows you to do this to the mobo and it will make the soundcard
not lock but work VERY poorly.

the new drivers in the main-line kernel fix this - but I've also had luck with
the drivers from 2.2.16-21 (from pinstripe)

Hi,
I've the same problem and I found no way to solve it. Hopefully this will be
fixed with the new version of sndconfig :-)

Bye, Duncan

I have the same problem on an Asus CUV-4X.  An easy solution is to install ALSA.

http://www.linuxnewbie.org/nhf/intel/hardware/southbridge_alsa.html

I feel that the fact that sndconfig writes /etc/modules.config before it has
ensured that
everything workes fine is a bug!

This should be changed. In addition, there is no reason why the sound stuff has
the
be loaded in level 1. The sound stuff should be removed from rc.sysinit and
moved
to /etc/init.d/sound.

# mount -n -o remount,rw /

mount: no such partition found

Ideas?

I've been bit by this problem twice recently; it would be rather awful for a
newbie.  Here is a patch
for sndconfig.c that does not rename /etc/modules.conf until all is hunky-dory. 
Thus I added a
few args to modprobe in TestSndCard() to use the '-C /path/to/file' arguments. 
I also copied the
config file instead of renaming it, so that there is no window-of-opportunity
for the file to 'disappear'.
I also check the return code of WriteConfModules() and added a bit of logic for
that. (and I'm not
sure why the sync() call was there - ? because of the rename() call?)  Email me
if you want the
patch via email..
I tested it on a system that succeeds, and a system that hangs hard and requires
a power reset.
The 2nd system came back okay with its original /etc/modules.conf file in place.

Same problem with an ABIT VA6. Nothing in the BIOS helped me.

The linux /bin/sh solution from alan worked with the following
modification:

mount -n -t ext2 /dev/hda7 -o remount,rw /

I'm not sure how many of those options were required, but it found the
partition. Whereas the command that he gave didn't find it on my system. But I'm
back up & running & I'm glad this bug database is here. 

I would *STRONGLY* vote for fixing sndconfig so that it does not overwrite
/etc/modules.conf until everything is OK.

patch added (more or less) in sndconfig-0.60-1; thanks!
