           Summary: [i915] Framebuffer ID error after suspend/hibernate
                    leading to X crash
           Product: Drivers
           Version: 2.5
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: high
          Priority: P1
         Component: Video(DRI - Intel)
        AssignedTo: drivers_video-dri-intel at kernel-bugs.osdl.org

        Regression: Yes


I've been experiencing X freezes and crashes for more than a year, and with
every kernel version the cause of the bug changes. After Linus pushed
985b823b919273fe1327d56d2196b4f92e5d0fae to 2.6.35rc6 (see below [2]), I'm now
getting an "invalid framebuffer id" error that kills my X server. Before that
commit, I was getting an oops, which was reported in bugs.fd.o as [1].


/var/log/kern.log:

At this point, the X server is killed, and won't restart:
Fatal server error:

    drm/i915: fix hibernation since i915 self-reclaim fixes

    Since commit 4bdadb9785696439c6e2b3efe34aa76df1149c83 ("drm/i915:
    Selectively enable self-reclaim"), we've been passing GFP_MOVABLE to the
    i915 page allocator where we weren't before due to some over-eager
    removal of the page mapping gfp_flags games the code used to play.

    This caused hibernate on Intel hardware to result in a lot of memory
    corruptions on resume.  See for example
