           Summary: Oops on reboot with two Radeons
           Product: Drivers
           Version: 2.5
     KernelVersion: 2.6.25
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI)
        AssignedTo: drivers_video-dri at kernel-bugs.osdl.org
        ReportedBy: linux at rainbow-software.org

Distribution: Debian unstable

Hardware Environment: x86_64, Radeon X1650Pro PCI-E, Radeon 7000 PCI

Software Environment: Debian unstable

Problem Description:
When I run X on both Radeons (X1650Pro with radeonhd driver, R7000 with radeon
driver), the following Oops appears when I issue a reboot command (it reboots
successfully after that). When I run X on either of the cards separately, the
Oops does not appear.
