           Summary: radeon dri detects different number of pipes each boot
           Product: DRI
           Version: XOrg CVS
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Radeon
        AssignedTo: dri-devel@lists.freedesktop.org

Hi,

Whenever I boot my system, I get either:

a) 3 pipes reported by dri. System works fine, and flash plugin works very
fast.

b) 1 pipe reported by dri. System works fine, and flash plugin works very slow.

On the log I get:

I.e., the line that reads radeon: 3 quad pipes, 1 z pipes initialized sometimes
changes to 1 quad pipes.

Loading/unloading the driver does not change that, only reboots/power cycles
do.
