It's really got a specific symptomology. I am almost tempted to say
it has something to do with powersaving/sleeping, as it only happens
when the system is idle, virtually always when the video is off
(although it runs for hours with the video off when I'm keeping it
busy) and like that. Of course I don't have any of the powerbook
power saving turned on or anything, but something is strange because
the way it hangs is so specific. It locked on me last night about
50 times, I was about to pull my hair out. I just had to remember
to type `sync' any time I was going to leave it alone for more than
a minute, assuming it wasn't compiling a kernel or something.
