    the last cd related errors were half a month ago. As a side note, the
    cdrom drive in this powerbook G3 (Lombard) only really worked right,
    if at all, 50% (or less) of the time in 2.6 (it's fine in 2.4). It
    does seem to work now (maybe due to the pmac patches in -mm?) though.
    I'll continue to test the drive after more uptime and a few
    sleep/wakeup cycles.
