Black screen freeze

Description of problem:
Toshiba NB555D froze with black screen. No response to CTRL-ALT-Fn, CTRL-ALT-DEL. Even disconnecting all USB devices and holding the Power
button for 15 seconds had no effect! (Fortunately, there was no traffic
on the USB removable disk, and I did a subsequent e2fsck to check the
journal recovery had worked properly.) There was also a Hauppauge analog
TV stick plugged in. I think I provoked the bug by running xawtv with no framebuffer parameter. If my parameters were incorrect, I should have gotten an error message. As it was, I had to remove the power and the battery before I could restart the machine.
The section of /var/log/messages is attached. Note the large block of zero bytes after Aug 21 09:48:45 localhost systemd-sleep: Suspending system...
Version-Release number of selected component (if applicable):
kernel-3.10.7-100.fc18.x86_64 #1 SMP
Only happened once.
Steps to Reproduce:
1. Tried to reproduce once, but did not succeed in getting a crash. It's the first time I've seen the power switch fail to turn off a laptop.
