[Intel-gfx] [i915gm] kernel warning: failed to unbind object for tiling switch

[Adam Lantos]

Hi all,


I've just got frozen rendering / xserver lockup on my i915gm (no
distortion, but only mouse cursor and sysrq works).
Xorg log and config are attached.

The device is
00:02.1 Display controller: Intel Corporation Mobile 915GM/GMS/910GML
Express Graphics Controller (rev 03)

Linux-2.6.30-rc3, libdrm-2.4.6, mesa-7.4, xserver-1.6.1,
xf86-video-intel 2.7 branch commit
296a986e5258e2fd13ec494071b7063bd639cd68.


I use KMS/DRI2/UXA.
Relevant kernel log entries are:
