Subject: Badness at kernel/time/timekeeping.c:98 in pmud (timekeeping_suspended) 

Got a couple of these on a PowerBook running 2.6.29-rc2 either during
suspend or resume -- it's hard to tell.  (The suspend message is
timestamped in syslog with the time I resumed, so I guess it was
buffered along with the subsequent "Badness" messages.)
