kernel panics
About a week or two ago, all my kernels started oopsing and panicking
on boot. It seemed to be happening as soon as i2c-keywest was being
probed (although I saw some messages referring Keywest earlier in the
boot process, so that may be wrong). This happened with all my
kernels, even though I hadn't changed a kernel configuration in
months. I booted of my kubuntu live cd and removed i2c-keywest. This
allowed me to boot, but sound no longer worked (very similar to
http://lists.debian.org/debian-powerpc/2006/02/msg00350.html). I also
couldn't seem to load or unload many kernel modules. I can't load
dmasound_pmac, although I don't know if that's related. I upgraded to
the most recent kernel-source in etch (2.6.15-7), dselected i2c
busses, compiled and installed. I at least seem to be able to use
verything except sound (and i2c, of course), but the kernel is still
oopsing (output is below).
Like I said, I haven't changed my kernel configuration in months. I
have been updating the bcm43xx module, but I don't think that's
changed in a while. A new version of udev enetered etch around that
time, so that may be related. The only other thing I did was install
ext2fsx on the Mac side. This coincided precisely with the breakage,
but since it's read only I'm not sure how this could have broken
anything. My machine is Powerbook G4 12" (February 2005 version).
Any guidance on how to fix this would be appreciated.

In 1997 a group of programmers started writing a desktop environment
to fix a travesty they didn't create. Their program promptly found
its way onto un*x systems everywhere. Today, still opposed by a
software monopolist, they survive as soldiers of fortune. If you share
their vision, if you know you can help, and if you can connect to
internet, maybe you can join... the K-Team.
