    Taking your suggestion I zeroed out the CF card, then used fdisk and
    newfs_msdos to get it in working order again. I've been testing it
    over the past week and have had no problems since.

    Thanks for the pointer. Is it accepted for a corrupt filesystem to
    freeze the system, though?

    I tried that, and doing a read and waiting a few seconds. Opening for
    write, as above, worked immediately.
