            Bug ID: 67876
          Assignee: dri-devel@lists.freedesktop.org
           Summary: linux v4.11-rc1 many drm:radeon_ttm_backend_bind ERROR
                    failed to bind 2025 pages issued during boot
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: jim.cromie@gmail.com
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: XOrg CVS
         Component: DRM/Radeon
           Product: DRI

during boot of linux 3.11-rc1+
apparently just after switch over to fb,
I get a raft of errors like this
(copied from a photo)

 [drm:radeon_ttm_backend_bind] *ERROR* failed to bind 2250 pages at 0x000000..
 [drm:radeon_gem_object_create] *ERROR* Failed to allocate GEM object
(always-same-tuple)
 size      : 888xxxxx bytes  
 alignment : 0 bytes
 domains   : 2

Eventually, they stop, and boot continues normally, and machine is functional.
If I hit escape (any key?) then the stream of errors is interrupted,
and systemd boot continues, again normally.

dmesg then contains many of these:
(almost exclusively these)

FWIW - git describe has apparently mis-labeled the kernel,
its not really v3.10-rc5+ but rather v3.11-rc1-minus

Ive git bisected it down to: (note the SHA match w kernel's -gXXX)

commit dc50ba7f9a6d9a920409892c7f30bce266067345
Author: Alex Deucher <alexander.deucher@amd.com>
Date:   Wed Jun 26 00:33:35 2013 -0400

    drm/radeon/kms: add dpm support for evergreen (v4)

    This adds dpm support for evergreen asics.  This includes:
    - clockgating
    - dynamic engine clock scaling
    - dynamic memory clock scaling
    - dynamic voltage scaling
    - dynamic pcie gen1/gen2 switching (requires additional acpi support)

    Set radeon.dpm=1 to enable.

    v2: reduce stack usage, rename ulv struct
    v3: fix thermal interrupt check notices by Jerome
    v4: fix state enable

The previous commit boots fine:

    drm/radeon/kms: add dpm support for rv7xx (v4)

dmesg for that kernel looked to have info thats pertinent 
to whats been done in Alex's patchset at this commit,
so heres the relevant parts.

So thats what I got right now.
I hope to try a few things myself soon, 
but I'll test a patch promptly.
