Every time I create/mount or unmount/detach a MFS filesystem,
powerd would *immediately* react with something like the
following:
### mdmfs -s 200m md /mfs
load 200%, current freq 600 MHz ( 9), wanted freq 1092 MHz
changing clock speed from 600 MHz to 1200 MHz
load 4%, current freq 1200 MHz ( 5), wanted freq 955 MHz
changing clock speed from 1200 MHz to 1000 MHz
### umount /mfs && mdconfig -d -u 0
load 200%, current freq 1000 MHz ( 6), wanted freq 1910 MHz
changing clock speed from 1000 MHz to 1982 MHz
or even
load 4%, current freq 1600 MHz ( 3), wanted freq 1519 MHz
### mdmfs here
load 100%, current freq 1600 MHz ( 3), wanted freq 4532 MHz
Is that expected behaviour? :-)
