Subject: [REGRESSION] Radeon (Evergreen) Crash with "pin failed" in Kernel 3.10-rc7

Hello all,

3.10-rc7,(at revision 98b6ed0f2) breaks evergreen on my system. I get
a crash soon after Ubuntu's Unity is loaded:

[  633.026429] SysRq : Emergency Remount R/O

The full dmesg output for that session is attached in dmesg.txt.

In the crash, X crashes and I am dropped onto the console tty. Only a
reboot works after this (although sysrq does work, so it is not a full
freeze).

My card is a Radeon HD 5000M Series. Specifically, it has PCI ID: 1002:68c1

I am running Ubuntu 12.04, but with upgraded libdrm, mesa and
xf86-video-ati packages, close to the GIT tip. Specifically:

libdrm: a0178c00c7 (June 5)
mesa: bbd2d575e (June 20)
xf86-video-ati: 3626ab147b67 (June 14)

*An important note:* In this 3.10-rc7, I have enabled UVD by
installing the correct firmware (indeed, I specifically wanted to test
UVD video decoding). But this crash occurred without my having tried
to use UVD.

Kernel 3.9.7 works fine on this card and with the DRM stack outlined above.

Let me know if I should provide further information. I am able and
happy to do all manner of debugging and testing, at your suggestion :)

Many thanks,
