Re: System Hangs on every other boot.

["Daniel Millen" <dmillen@aa.net>]

Weird.  I just turned power management on (when I am plugged in), and it seems
to work now.  I've rebooted about 10 times, and it works fine.  That's definately
something that I wouldn't have expected to cause a problem.  Usually power management
causes a problem when it's ON.
