https://bugs.freedesktop.org/show_bug.cgi?id=110931

            Bug ID: 110931
           Summary: Timeout initializing Falcon after cold boot
           Product: xorg
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
          Assignee: nouveau at lists.freedesktop.org

Failing kernel log

I've got a fairly recent Dell/Alienware GTX 1080. It fails on
initializing/resetting the Falcon during boot, and is not usable by Xorg
subsequently. See *-bad.log attachments.

Workaround: boot into Windows, and reboot into Linux. Everything works fine
after that. See *-good.log attachments.

Initialization timeout happens in acr_ls_sec2_post_run(), in
ls_ucode_msgqueue.c. The corresponding Xorg driver error message is "Failed
to
initialise context object: 2D_NVC0 (0)"
