kapm-idled eating up my CPU

[Oki DZ <okidz@telkom.net>]

Hi,

Recently I switched the kernel to the 2.4-test10 version, and I then I
have the following:
PID USER  PRI  NI  SIZE  RSS SHARE STAT LIB %CPU %MEM   TIME COMMAND
  2 root   17   0     0    0     0 SW     0 26.8  0.0 184:02 kapm-idled

Why is that...?
BTW, I use Debian 2.2 on an Intel machine.

Thanks in advance,
Oki
