ALSA: Here is the answer to 'unresolved symbol schedule_work'


Thanks to Clemens Ladisch over at the ALSA-user mail archive, I happened upon the answer and thought I would post the original problem and the solution that fixed it.

Earlier today I posted that during an install of ALSA on my RH9 distro, I encountered a few error messages when trying to execute:
modprobe snd-intel8x0. I received the following error messages:

/lib/modules/2.4.20-24.9/kernel/sound/acore/snd.o: unresolved symbol schedule_work

/lib/modules/2.4.20-24.9/kernel/sound/acore/snd.o: insmod (previous directory string) failed

/lib/modules/2.4.20-24.9/kernel/sound/acore/snd.o: insmod snd-intel8x0 failed

Texicle was kind enough to provide me with some answers, which ultimately spawned my further Googling of the error message. Over on the ALSA-user mail archives page I found my answer:

1)After unpacking all of the contents in the alsa-drivers-xxx package, run your ./configure (/cvscompile, make build, etc... on your system) and then immediately peform the following steps BEFORE you execute make and make install:

mkdir -p include/linux
touch include/linux/workqueue.h

2)Once this is done, proceed with the commands make; make install (note, I had FUBAR'ed the first step sooo many times that I actually ran <make clean> before <make> in order to flush the system and it worked well).

3)Now move on to unpacking, configuring, and installing your alsa-libs-xxx and alsa-utils-xxx packages.

I hope this helps someone else out there. Now, if I can only figure out how to make the sounds come through the speakers!!! After ensuring that all volume controls (native and nonnative) are NOT muted, still I am sans sound. However, at least the friggin' thing finished the install and all of the snd- devices come up on lsmod.

Unresloved Symbol

Well you have a great post because I had the same problem. But Alsa verison 1.0.1 is broke they just posted verison 1.0.2 and the problem was fixed no more sound problems.
