Recent update to RELENG_6 creates lots of calcru warnings

[James Long]

I'm running FreeBSD RELENG_6 on a Compaq DL380 G2 dual PIII-1.4GHz with 
an SMP kernel.  dmesg below.

Prior to about August 12, the system had been quite stable.

Since that time, I am finding lots of calcru warnings, which often
cause system services to fail when they see unorthodox time shifts.

Section 5.19 of the handbook appears not to be current any longer,
suggesting setting kern.timecounter.method=1.  
kern.timecounter.hardware=i8254 also does not improve things.

Other suggestions?

Thanks,

Jim
