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 ReportedBy: alexandre.nunes@gmail.com
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.
