On my dual opteron, I get flipping perhaps a handful of times per day 
(5.4-PRE/amd64 from march 22).

On my Xeon EMT64 with hyperthreading (5.3-STABLE/amd64 from Jan 7), it 
happens every 2-6 hours.

My 5.3-REL/i386 Xeon with hyperthreading does it about two or four 
times per day, no resetting.

Neither one shows time step resets.
