--- Comment #1 from Jochen Breuer <brejoc@gmail.com> ---
I'm now having exactly the same problem with an older Samsung NC10 - a so
called netbook.

'kern.eventtimer.timer' defaults to 'HPET'. But in this case the solution s=
eems
to be 'LAPIC'.



--- Event timer choices ---

$ sysctl kern.eventtimer.choice
kern.eventtimer.choice: HPET(450) HPET1(440) HPET2(440) LAPIC(400) i8254(10=
0)
RTC(0)


--- Intel Atom CPU N270 ---

$ sysctl hw.|head
hw.machine: i386
hw.model: Intel(R) Atom(TM) CPU N270   @ 1.60GHz
hw.ncpu: 2
hw.byteorder: 1234
hw.physmem: 1042579456
