You might as well have
powerd_enable="NO"

I have an HP nx6125 that will randomly hang if powerd is enabled and
if you search back through the mailing lists, there are a few other
people with similar problems.  I've done some experimenting and in my
case, it's the clock speed transitions that cause a hang.  The actual
clock speed is irrelevant.  I believe it's a race condition or a
timing bug.
