BUG: unable to handle kernel paging request at 0010afb0

appeared after a suspend failed, which might i turn have had somethign to do with the fact that I had disconnected a USB modem in a hurry while shutting down.

In general suspending with Karmic seems to be a stately process: just pulling out the power cord an dshutting the lid in a hurry will quite often produce a mysterious hang of this sort.
