I cannot say for sure if hibernating is necessary to trigger the problem
or not... every time I've seen the problem, it's been after using
hibernate-ram a couple of times, but I also haven't left the laptop
running continuously for a couple of days before. I usually carry my

on continuously. It definitely doesn't happen immediately after
resuming from suspend, though. I can resume from suspend, watch some

This bug is the only issue preventing me from switching exclusively to
linux, so I really hope to find a fix for it -- I just don't know where
