           Summary: CPU soft lockups with KMS
           Product: xorg
           Version: 7.4
          Platform: Other
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org
        ReportedBy: mikko.cal at gmail.com
         QAContact: xorg-team at lists.x.org


I'm not sure about when exactly this happens or if it's somehow random or
related to my other long-standing bug report about random hard-lockups (
http://bugs.freedesktop.org/show_bug.cgi?id=16198 ).

Anyway, with KMS enabled I got this in my log:
