           Summary: VLC crashes on fullscreen with GLX output and
                    colortiling enabled
           Product: Mesa
           Version: 7.9
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/R600
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: bio_tube@yahoo.com


It works in window mode, but it crashes the instant it switches to fullscreen,
giving the familiar "drmRadeonCmdBuffer: -22. Kernel failed to parse or
rejected command stream. See dmesg for more info."; I've checked and this isn't
fixed in master, either; r600g performs as expected, so this is definitely a
Mesa bug(I've already pulled the latest in the 7.9 branch). dmesg gives the
following:

[ 1953.411625] radeon 0000:02:00.0: r600_cs_track_validate_cb:220 cb height
(724) invalid
[ 1953.411630] radeon 0000:02:00.0: r600_packet3_check:1252 invalid cmd stream

Should be fixed with this patch:
http://git.kernel.org/?p=linux/kernel/git/airlied/drm-2.6.git;a=commitdiff;h=8f895da57da80b307efa2f94b5d4caf801e959a5

I pulled the drm-core-next branch in order to apply the pageflipping patches(I
also pulled drm-radeon-testing before that to apply the first batch), so I've
got the patch.

Are you sure you've booted the right kernel?  You should never hit that message
with the patch applied.  Also, the line numbers indicate a non-patched kernel.

That was it - I've got two kernels(2.6.36-amd64-drt-pageflip+ and
2.6.36-amd64-drt-pageflip2+); GRUB2(GRUB classic stopped working for me) got
them in the wrong order(placing the former before the latter), so I swapped
them in grub.cfg, which apparently got regenerate somewhere along the line,
leaving me with the first round of pageflip patches. I've deleted the old
kernel to make sure this doesn't happen again.
