To whom it may concern,

I have an issue with with FreeBSD 6.1-BETA4 what I was hoping you could 
help address:


The kernel timecounter tests show that the ACPI timer is way, way off, 
and I regularly get these messages from the scheduler:

    calcru: runtime went backwards from 4303326 usec to 3738581 usec for 
pid 28 (irq17: em3)
    calcru: runtime went backwards from 19454204 usec to 16704508 usec 
for pid 1 (init)
    calcru: negative runtime of -710189 usec for pid 84768 (as)
    calcru: negative runtime of -710179 usec for pid 3477 (as)

Running something like 'sysctl -a' will cause the scheduler to spew 
these errors and completely stop process execution for a noticable 
period of time. Other than this, the machine works without error.

Thanks for your help.

Regards,
