           Summary: 120 wakeups/s with Radeon XPress 200M
           Product: xorg
           Version: unspecified
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org
        ReportedBy: jkohen at users.sourceforge.net
         QAContact: xorg-team at lists.x.org


I noticed my XPress200M is doing 120 wakeups/s on my laptop. I'm using XOrg
7.3/1.4.1~git20071119, radeon 6.7.196 and Mesa 7.1~20070824. DRI and Composite
are enabled (but Xorg is the only client according to /dev/dri/card0). The
kernel is 2.6.23.9 and I'm not using dual-heal, only the laptop's panel.
However, I do have several devices defined in xorg.conf (since I used to have a
CRT), but only the panel is referenced in the current screen layout "Single
LVDS" (see attached).

I just found out that xrandr reported VGA-0 on unknown connector. I used xrandr
to disable it and the wakeups went down to 0. Which allowed the CPU to reach
state C3. Then I set it back to auto and the wakeup count went again up to 60.
I set it back off, but it stayed in 60 and the CPU doesn't reach state C3
anymore. This seems buggy. Also, I have nothing plugged to VGA-0, so it should
be off by default, right?
