           Summary: resume to black screen
           Product: Drivers
           Version: 2.5
    Kernel Version: 3.5.0-3
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - non Intel)
        AssignedTo: drivers_video-dri@kernel-bugs.osdl.org
        ReportedBy: energonic@gmail.com
        Regression: No


System: iMac 11,2 (mid2010) with AMD radeon 4670.
kernel 3.5.0-3 used on ubuntu 12.10. No swap partition.
Boot requires nomodeset on kernel command line, else black screen (even for
text-only boot. Radeon module disconnects wrong display port).

Resume after suspend shows black screen, but reboots using Ctl-Alt-Del, so has
resumed from suspend. Suspect kms invoked on resume and radeon disconnects
wrong display port.

Same behaviour on archlinux using kernel 3.4.4-1.
