           Summary: RadeonKMS segfaults kdm on mobility radeon x700 pcie
           Product: Drivers
           Version: 2.5
    Kernel Version: 2.6.32
          Platform: All
        OS/Version: Linux
              Tree: Fedora
            Status: NEW
          Severity: high
          Priority: P1
         Component: Video(DRI - non Intel)
        AssignedTo: drivers_video-dri@kernel-bugs.osdl.org
        ReportedBy: kontrollator@gmx.de
        Regression: Yes


Using the KMS option of the radeon-driver makes the kernel segfault and reboot
when starting an kde session. This happens on daves radeon-testing tree using
latest mesa-git and libdrm-git. Also happens on latest linus tree. The same
combination works great when using the non-kms codepath.

Hardware is an mobility radeon x700 pcie.

caught.

Disabling pci-msi per boot option pci=nomsi,routeirq fixes the problem, Xorg
starts, no crash, proper counting of interrupts.

Broken MSIs is a motherboard chipset issue rather than a radeon bug.  Your
motherboard chipset may need a quirk or to disable MSIs altogether.

Correct.  I'm not sure how to change it.  It wouldn't let me change it either.
