Fedora 17 suspend / resume problem

Getting a screen full of white and black pixels when trying to resume operation on a laptop.

Suspend operation in one of two ways:

1) simply close the cover
2) select "suspend" from the menu

By resuming, I mean to try to turn on the laptop again.

I get a bunch of "failed" messages re. channel 1, channel 2, etc. followed by a full screen of white/black pixels followed by the same failed messages. These scenarios keep repeating.

Any suggestions about this. Its very annoying to try to resume operations, only to have to do a hard reboot.
