I don't think this accounts for all of his problems, unless his
machine has an unusual configuration.  Alexander and I recommended
that he try different clocks, and just recently, for example, he wrote
that he had used:

loader.conf
hint.apic.0.clock="0"
hint.atrtc.0.clock="0"
hint.attimer.0.clock="0"
hint.hpet.0.legacy_route="1"
machdep.disable_rtc_set="1"
kern.eventtimer.timer2="HPET"
kern.eventtimer.timer1="NONE" (Or, if available, HPET1, ...)
kern.eventtimer.singlemul="1"

sysctl.conf:
kern.timecounter.hardware=HPET

and reported that it did not help.  The HPET doesn't usually suffer
from the problem that you are describing, right?
