           Summary: [i915] [MSI 7817] kernel 3.16.0: "drm failed to set
                    drm interface version: Permission denied (13)"
        QA Contact: intel-gfx-bugs at lists.freedesktop.org
          Severity: critical
    Classification: Unclassified
                OS: Linux (All)
          Reporter: jens-bugs.freedesktop.org at spamfreemail.de
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: XOrg CVS
         Component: DRM/Intel
           Product: DRI

After upgrading to 3.16.0 from -rc2, I cannot start X any more. Log file of
starting X with both kernels attached. The important differences is the
following:

 (EE) intel(0): [drm] failed to set drm interface version: Permission denied
[13].
 (EE) intel(0): Failed to claim DRM device.
 (II) UnloadModule: "intel"
 (EE) Screen(s) found, but none have a usable configuration.

in the log file with 3.16.0. 

What can this be? Any ideas?

Thank you!
