>Description:
After upgrading from a 5.1-RELEASE GENERIC kernel to RELENG_5_2 checked out 13.Dec I get constant messages like this:

calcru: negative time of -1850925 usec for pid 9077 (vdelivermail)
calcru: negative time of -1780981 usec for pid 9077 (vdelivermail)
calcru: negative time of -780102 usec for pid 9084 (vdelivermail)
calcru: negative time of -711217 usec for pid 9084 (vdelivermail)
calcru: negative time of -2783882 usec for pid 9087 (vdelivermail)
calcru: negative time of -2713929 usec for pid 9087 (vdelivermail)
calcru: negative time of -988197 usec for pid 9086 (sh)
calcru: negative time of -929586 usec for pid 9086 (sh)
calcru: negative time of -969496 usec for pid 9069 (qmail-local)

It seems processes die now and then as well. Also, I had a total system lockup, machine didn't even respond to BRK on the serial-console.

Machine is an Enterprise 450 with 2x250 (248Mhz) CPUs, 384mb ram. Only the internal SCSI controllers are used. 1 hme interface. Serial console only. From dmesg.boot:

Timecounter "tick" frequency 248000000 Hz quality 0
initialializing counter-timer
Timecounter "counter-timer" frequency 1000000 Hz quality 0 (Repeated 3 times)
Timecounters tick every 10.000 msec
