Subject: Regression: monitor fails to sleep/suspend, forced to reboot to 
	correct. 2.6.34-rc6

Hi,

My current setup has worked on previous kernels, I think the problem
has begun with 2.6.32.

If the monitor goes to standby/suspend it shows:

"Out of Range

H.frequency 33 KHz
V.frequency 31 Hz"

I can test this with running: "xset dpms force standby" or "xset dpms
force suspend".

I can no longer switch to console with Ctrl+Alt+F2, etc, and must
reboot to be able to use my system again.

Please advise what additional information/testing I can provide to
make sure this regression gets fixed for 2.6.34.

This bug appears to affect all recent distros as they are 2.6.32 based
(ubuntu lts, debian, rhel6).

I have reported the following bugs with little response. I am unsure
whether I have filed bugs in the correct place or against the correct
component.

Please CC me in on any replies.

Thanks,

Lex.
