No earthly notion. I never figured out exactly how it happens. Setting traps for the critter didn't worked out. I did receive some diagnostic info from a group of ppc64 boxen that indicated that the clock went backward, but when I zeroed in on it, it they went silent. All other machines with traps set have been totally silent for months (that's a lot of machines too).
Bug seems to be dead upstream, at least I haven't noticed any reports with a recent kernel.
