I wonder if that's the same bug that's breaking autofs for me.

Oct 22 14:39:01 kenny automount[2299]: cache_readlock: mapent cache
rwlock lock failed
Oct 22 14:39:01 kenny automount[2299]: unexpected pthreads error: 11 at
65 in cache.c

I'm bisecting 2.6.23-mm1 today to find the problem patch, with
some luck I'll have it this afternoon.

With the series applied up to whitespace-fixes-task-exit-handling.patch
things work.

It breaks before kswapd-should-only-wait-on-io-if-there-is-io.patch

That leaves only about 60-80 patches to look at :)
