Has this been pushed or has the problem been solved somehow? Time is
against us on this bug as more boxes will crash as they reach 200 days
of uptime...

In any case, feel free to use me as a Reported-by, my full report of the
problem being <20110430173905.GA25641@xxxxxx>.

FWIW and if I understand correctly, my symptoms were caused by *two*
different bugs:
a) the 54 bits wraparound at 208 days that Peter fixed above,
b) a kernel crash at ~215 days related to RT tasks, fixed by
305e6835e05513406fa12820e40e4a8ecb63743c (already in -stable).
