Hi.

I realized that kernel thread apm0 ate much CPU time.  Here is
top(1)'s display on my note PC.


load averages:  0.09,  0.10,  0.08                                     12:38:24
56 processes:  53 sleeping, 2 stopped, 1 on processor
CPU states:  0.5% user,  0.0% nice,  0.5% system,  0.0% interrupt, 99.0% idle
Memory: 69M Act, 7132K Inact, 3860K Wired, 20M Free, 165M Swap free

  PID USERNAME PRI NICE   SIZE   RES STATE     TIME   WCPU    CPU COMMAND
  240 root       2    0  9196K   17M sleep    27:31  0.05%  0.05% XF86_SVGA
    5 root      10    0     0K 9100K sleep   423:52  0.00%  0.00% apm0
  299 taca       2    0  7764K 8892K sleep     9:42  0.00%  0.00% emacs
  285 taca      18    0   460K  888K sleep     1:22  0.00%  0.00% xearth
	...

Is it natural consequence or some problem on apm driver?
