remenda Level 1 Level 1 (0 points)
I am having an issue where the kernel is consuming an inordinate amount of CPU time. I am not sure whether the number given by activity monitor is a percentage, but it's ~150.

I have run dtrace on the kernel and it seems that it's spending a lot of time in the log_level function:

twiggy:Documents remenda$ sudo ./hotkernel.pl
Password:
Sampling... Hit Ctrl-C to end.

FUNCTION COUNT PCNT
<snip>
machkernel`ml_set_interruptsenabled 2049 5.3%
machkernel`machineidle 9827 25.4%
machkernel`loglevel 22406 57.8%

My CPU temperature is 66 degrees C. Both cores are active, so I believe this problem to be distinct from the temperature-related core shutdowns in other threads.

Macbook Air, Mac OS X (10.5.4)
