Dan, is that machine equipped with Hyperthreading?
Attilio
Yes. It's an Intel Atom 330, which is a dualcore CPU with HT (4 cores
visible in "top" as a result)
Yes, mine is also Atom 330.
I cannot test the patch because my machine is also in production now.
But I have tested it with hyperthreading.
powerd with HyperThreading -> spin lock hold too long
powerd without HyperThreading -> no problem
no powerd with/without HyperThreading -> no problem
This blog article also describe the same situation:

By the way, I found that the readings of coretemp don't significant
change when I enabled powerd so that I doubt that powerd may not be very
useful for Atom CPU?
Thanks very much,
C.C.
