    Miquel van Smoorenburg <miquels@cistron.nl> forwarded me this fix to
    resolve a deadlock condition that occurs due to the API change in
    2.6.13+ kernels dropping the host locking when entering the error
    handling. They all end up calling adpt_i2o_post_wait(), which if you
    call it unlocked, might return with host_lock locked anyway and that
    causes a deadlock.
