        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.

        https://bugzilla.redhat.com/show_bug.cgi?id=581898

        Please CC me in on any replies.

        Thanks,

        Lex.

    Can you do a bisect?
    (2.6.32 - HEAD shouldn't
    take too long).

I'm still a git newbie. What specific command should I run and what
output to post?
You want me to do it against HEAD vs "latest known working version"?

Thanks,

Lex.
