[Problem]
render error hit, after series of I/O errors on sr0.  The I/O errors first displayed during boot immediately after drm was initialized, the render error only later on.

[Original Description]
Occurred while watching an encrypted DVD in VLC. The video started lagging behind the audio as these crashes were popping up.

...later...
Actually, assuming it is the same crash, I'm getting these pop-up without watching a DVD, so that seems to be unrelated.

commit 14667a4bde4361b7ac420d68a2e9e9b9b2df5231
Author: Chris Wilson <chris@chris-wilson.co.uk>
Date:   Tue Apr 3 17:58:35 2012 +0100

    drm/i915: Finish any pending operations on the framebuffer before disabling
    
    Similar to the case where we are changing from one framebuffer to
    another, we need to be sure that there are no pending WAIT_FOR_EVENTs on
    the pipe for the current framebuffer before switching. If we disable the
    pipe, and then try to execute a WAIT_FOR_EVENT it will block
    indefinitely and cause a GPU hang.
    
    We attempted to fix this in commit 85345517fe6d4de27b0d6ca19fef9d28ac947c4a
    (drm/i915: Retire any pending operations on the old scanout when switching)
    for the case of mode switching, but this leaves the condition where we
    are switching off the pipe vulnerable.
    
    There still remains the race condition were a display may be unplugged,
    switched off by the core, a uevent sent to notify the DDX and the DDX
    may issue a WAIT_FOR_EVENT before it processes the uevent. This window
    does not exist if the pipe is only switched off in response to the
    uevent. Time to make sure that is so...
