SubjectRE: Linux 2.2.2pre4 SMP crash (wait_on_bh)
This just happened to use twice more on the ASUS board which appeared to
have originally solved it (running 2.2.2pre4). Exactly the same symptoms.
Always CPU #0 waiting for #1 it looks like. I have just put pre5 on it
which looks like it has a bunch of SMP changes. Maybe it will fix
something (that would be nice :)).
