[Bug 32402] New: Oops associated with radeon_unpin_work_func

https://bugzilla.kernel.org/show_bug.cgi?id=32402

           Summary: Oops associated with radeon_unpin_work_func
           Product: Drivers
           Version: 2.5
    Kernel Version: 2.6.38.2
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: high
          Priority: P1
         Component: Video(DRI - non Intel)
        AssignedTo: drivers_video-dri <at> kernel-bugs.osdl.org
        ReportedBy: smf.linux <at> ntlworld.com
        Regression: No

If this system (LFS build) is left idle for several hours with xscreensaver
running(don't currently know which screen saver app. I am assuming one of the
Mesa 3D ones) the system will oops. The system is locked solid and there is no
trace in messages.old on reboot. The attached jpg is a photo of the screen at
system failure. I first noticed the problem in 2.6.38-rc8 but have waited until
now to report the problem in the hope of obtaining a more repeatable scenario.

Version info:

Xorg server 1.10.0
Xorg ati driver 6.14.1
libdrm-2.4.24
Mesa-7.10.1

[PATCH] drm/radeon: Fix an always-false-comparison

From: Liu Yuan <tailai.ly <at> taobao.com>

In the function atom_op_delay() of drivers/gpu/drm/radeon/atom.c,
the comparison performed in the udelay() is always false due to
that the unsigned-char is compared to an integer 20000.

[Bug 35861] New: [r300g] Oilrush: whiter triangle between center of the screen and horizon

https://bugs.freedesktop.org/show_bug.cgi?id=35861

           Summary: [r300g] Oilrush: whiter triangle between center of the
                    screen and horizon
           Product: Mesa

terminal output

There is a strange triangle of whiter area and missing effects between screen
center and horizon in Oilrush.

I'm attaching terminal output, however I don't think there is anything
important, just a few of: 

Mesa warning: glDraw[Range]Elements(start 130, end 877, count 1650, type
0x1403, indices=0x1c2)
    end is out of bounds (max=876)  Element Buffer 31 (size 3750)
    This should probably be fixed in the application.
