Alright so I tried to do a bisect when I noticed that building a knwon
to work -rc5 did no longer work either. Thought it might be a gcc
problem (gcc-4.3 here) so upgraded to 4.4 - same thing.
Then I recognized that it crashes on loading basically *any* module,
tried tun and applesmc. Attaching the crashes...

I am starting to run out of ideas...

from what I remember wait status failed debug message was
removed from the kernel(but could be wrong).
could you maybe have some type of userspace thing going on
causing this? i.g. running the latest git(on a macbook)
with a from scratch system with nothing of that sort,
or at least cant reproduce your error.

OK, I've found the culprit: binutils-gold

I build all kernels upto and including -rc6 with the old binutils and
since then have upgraded to binutils gold 2.20-4 which - in contrast to
the old binutils - uses --no-add-needed per default.

So I suspect it triggers an error(?) in the way how the kernel links
modules: It is now required to provide all needed libraries to the
linker when building the modules. I guess this problem could be worked
around by adding --add-needed to the LDFLAGS_MODULE ...

tough to say... some how your hitting
__wait_status during your initial boot.

by looking at the comment(in applesmc.c):
__wait_status - Wait up to 32ms for the status port to get a certain value
* (masked with 0x0f), returning zero if the value is obtained.

maybe your hitting a different value because of binutls.
(keep in mind I have the latest binutils running on the macbook,
but nothing switched to gold during compilation time)

That tells you there's something wrong with the device -- and maybe the
driver is misbehaving by telling mac80211 that it couldn't scan but then
still calling scan_completed().

In any case, driver bug as far as I can tell.

Oh and it's also not /this/ bug for sure, it just happens to hit the
same WARN_ON(), but the cause is very different.
