Hmm. I am getting resets on my amd64.
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.
On my little LAN here I have one machine syncing with the Internet that acts as a time server for 3 others. The time server machine (733MHz P3 w/ 4BSD scheduler), named 'www', logs the following:

2 of the clients (800MHz P3 and Althon XP 1800+, both w/ 4BSD scheduler) don't have any weird issues at all. The third (4x 550MHz P3 Xeon w/ ULE scheduler), aptly named 'quad', hasn't flipped much but has a lot of resets:

Note that all machines are connected to the same 100Mbit switch and were rebooted at the same time. I only got resets on the SMP/ULE machine. Perhaps SMP or ULE make the issue worse?
