	Machine is a SMP system, two PIII/866Mhz, Main PCB is ASUS CUR-DLS, 1GB ECC reg. RAM,
	machine is configured to operate as UP system.
>Description:
	Since BETA7 I get stuck on console, within a X11 session or while compiling 
something, after a while I can read something about "calcru: runtime went backwards ..." or
"calcru: negative time ...", the machine freezes and then crashes or get completely stuck.

I realized this shortly after an update from BETA6 I installed freshly from scratch after a total loss 
of the system, which occured after an upgrade from BETA6 to BETA7.

The now installed system runs well for a hort time, say 12 hours with SMP disabled, the crashes.
The previous system got stuck very shirtly after reboot by similar "calcru: ..." problems.
