Hi,

I'm hoping someone has a solution to this issue. I have a set of RAID arrays
that are not part of my root file system. Normally they are inactive.
However, when I ENABLE laptop-mode on my system, the drives are written to
every couple of seconds by pdflush. I am on Ubuntu 9.04 on a desktop system.
Here is my laptop-mode.conf file:

VERBOSE_OUTPUT=0
ENABLE_LAPTOP_MODE_ON_BATTERY=1
ENABLE_LAPTOP_MODE_ON_AC=1
ENABLE_LAPTOP_MODE_WHEN_LID_CLOSED=0
