hi,
i incurred in the same problem since two days, when i decided to upgrade 
my alsa driver from 0.9rc6 to 0.9rc7

some info:

i use a toshiba s3000-214 with an intel8x0 audio device

with 0.9rc6 alsa was running fine

i run debian unstable.


these are the relevant (!) package:

andrea@nb-venturi:~$ dpkg -l | grep alsa-
ii  alsa-base      0.9.0rc7-2     ALSA driver common files
ii  alsa-headers   0.9.0rc7-2     ALSA driver header files
rc  alsa-modules-2 0.9+0beta10+5+ Advanced Linux Sound Architecture 
(drivers)
ii  alsa-source    0.9.0rc7-2     ALSA driver source
ii  alsa-utils     0.9.0rc7-1     Advanced Linux Sound Architecture (utils)

andrea@nb-venturi:~$ dpkg -l | grep gcc
ii  gcc            3.2.2-0        The GNU C compiler.
ii  gcc-2.95       2.95.4-15      The GNU C compiler.
ii  gcc-3.0        3.0.4-13       The GNU C compiler.
ii  gcc-3.0-base   3.0.4-14       The GNU Compiler Collection (base package)
ii  gcc-3.2        3.2.3-0pre1    The GNU C compiler
ii  gcc-3.2-base   3.2.3-0pre1    The GNU Compiler Collection (base package)
ii  libgcc1        3.2.3-0pre1    GCC support library
rc  libstlport4.5g 4.5.3-4        gcc3-version STLport C++ class library
ii  libstlport4.5g 4.5.3-5cjh2    STLport C++ class library compiled 
with gcc3

under /usr/src there was:

andrea@nb-venturi:~$ ls -l /usr/src/
totale 31756
-rw-r--r--    1 root     root      2157649 2003-02-07 12:16 
alsa-driver.tar.gz

that is the debian way to put source tarball to upgrade some driver..

i compiled the usual stuff /usr/src/modules/alsa-driver

ad i installed all the modules with "make install"

than, at next reboot, the /etc/init.d/alsa script failed to run because 
there was a small glitch at line 93: a missing double-quote around 
$alsa_version

the i had to add /etc/modutils/alsa with all the aliases for the modules 
and i was up & running, or, at least, i was thinking.. :-(

the snd-intel8x0 goes up, from dmesg:

PCI: Found IRQ 10 for device 00:1f.5
PCI: Sharing IRQ 10 with 00:1f.3
PCI: Sharing IRQ 10 with 00:1f.6
PCI: Sharing IRQ 10 with 02:01.0
PCI: Sharing IRQ 10 with 02:04.1
PCI: Setting latency timer of device 00:1f.5 to 64
intel8x0: clocking to 48000

but, if i try a "cat /proc/asound/version"

i get an oopps

and the very same oops in dmesg

that's all. having not much more skill and time, i'll live without audio 
for some time hoping in better times! ;-)
