Ubuntu 8.10 froze around midnight UTC (Score 1)

My Ubuntu 8.10 system froze around midnight GMT. There's nothing in the logs to indicate any problem, except that the last log entry is at Dec 31 15:55:02 (that's 5 minutes before midnight) for a cron job that runs every 5 minutes. I wasn't at home at the time, so I didn't see what happened, except that my ssh connection died.

When I got home a few hours later, the system was still powered on (the fan was running), but the screen was blank. I was able to reboot it with no problem.

It's not the same problem as on the Zune, since that hit 24 hours earlier. It *might* have something to do with the leap second, or maybe it's a problem that occurs at the end of the 366th day of the year.

I suppose I could set the clock back and run it through midnight again. I'm not sure I'll bother, but if somebody else wants to try it it would be interesting to see the results. Or maybe I'll try that with a live CD.
