    There're a couple of known problems in booting the latest mmotm,
    2009-09-14-01-57, on T60p.

    The first is passing a NULL pointer to a workqueue from
    clocksource_mark_unstable(). This is fixed by reverting 7285dd7
    "clocksource: Resolve cpu hotplug dead lock with TSC unstable" from the
    x86 timers/core tree; Martin's fix had no affect on this crash.

    [ I notice Thomas has since provided patches for this problem, so I'll
    check if it solves this issue on T60p. ]

    The second is an issue with the i8042 driver's laptop table not being NULL
    terminated. This is fixed by Jin Dongming's patch at
    http://marc.info/?l=linux-kernel&m=125263897713267.

    The config you attached, however, is very different from
    mmotm-2009-09-14-01-57, so perhaps try this kernel with the above two
    fixes to see if you can successfully boot?
