Alan,

I'm aware of someone else seeing the same thing - they were using ac9,
but moved to ac13 and saw the problem (they didn't try ac12). They
have the following filesystems mounted:

mort:~# more /proc/mounts
none / shm rw 0 0
none pipe: pipefs rw 0 0
none / proc rw 0 0
/dev/root / ext2 rw 0 0
proc /proc proc rw 0 0
devpts /dev/pts devpts rw 0 0
/dev/hda1 /mnt/dos vfat rw 0 0
/dev/hda6 /mnt/data vfat rw 0 0

I've just asked them not to mount vfat at boot, and it still dies in the
same way (buffer.c:2443).

If it is filesystem related, then that leaves the following filesystems
still under suspicion:
        shm
        pipefs
        proc
        ext2
        devpts
