Post subject:  M3N78-VM and KM Testing

Hey -

So I've got the above motherboard, which I don't think KM agrees with. Various segfaults etc during install and general instability.

I'm guessing because it's a fairly new mobo.

Here's a link:

Is there anything I can do to assist in making KM capatible with this mobo?

Thanks,
Brad

I'd hate to tell you this, but you'll need a cutting edge/bleeding edge kernel. Someone in IRC recently had a similar board and we tried everything we could come up with, but it would not work. You can try installing R5.5 on some other hardware, update/recompile a newer kernel from kernel.org and then try to hook up the hard drive to your MCP78 (GeForce 8200) mobo. That's all you can do with KnoppMyth. You can alteratively try a different distro. Fedora 9 is rumored to support this chipset.

Well this isn't really KM specific, but I figured I'd post my progress:

I've got spdif audio working now; however, I had to make these changes in ALSA .17:

alsa-kernel/pci/hda/hda_codec.c function snd_hda_parse_pin_def_config, it starts at line 2813

Modify the switch statement:

switch (get_defcfg_device(def_conf)) {

and add at the bottom:


case AC_JACK_DIG_OTHER_OUT:
cfg->dig_out_pin = nid;
break;

Recompile:

./configure --with-cards=hda-intel; make; make install
rmmod snd-hda-intel && modprobe snd-hda-intel

To check that your change applied:

cat /proc/asound/version

Should read the date you just compiled it on.

If it doesn't

rpm -e alsa-driver-1.0.17-70.fc9.i386
rpm -e alsa-kmdl-2.6.25.11-97.fc9

reboot

now do

cat /proc/asound/version

Should read the date you just compiled it on.

Unmute iec958 in your alsamixer and run:

speaker-test -twav -c2 -Dhw:0,1

To test your sound. You should hear some voices.

Sometimes there are permission issues:

chmod -R a+rwX /dev/snd/.
chmod -R a+rwX /dev/adsp
chmod -R a+rwX /dev/dsp

Should fix it.
