So feel free to drop to /dev/null until I can reproduce on a clean and recent kernel. (But -rc3 didn't boot for me, and I don't have anything else handy atm.) By bashing on random device nodes (with mknod + mmap as root), I got a few messages of this kind: idr_remove called for id=236 which is not allocated.

Or is it purely my own fault?
