           Summary: 2.6.32.2 KMS enabled hangs on boot on ATI RV730XT
                    [Radeon HD 4670]
           Product: xorg
           Version: 7.4
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org

         QAContact: xorg-team at lists.x.org


same setup as in bug #25460

After compiling the new stable kernel, if radeon.modesetting is enabled the
sytem hangs at boot. Some lines are printed (indicating the beginning of the
boot process) then the screen gets blanked and stays turned on, while
everything else doesn't respond (keyboard, disk).

This doesn't happend if I disable radeon modesetting and it doesn't happen with
the 2.6.32.1 kernel and modesetting enabled. Under the latter I still
experience bug #25460.

Sadly I cannot offer any logs because they don't get written yet.

Any ideas before figuring out problematic commit out of the ones in the
2.6.32.2 package, or should I go and bisect which could take a while...
