Bug Description

SharkBay(Desktop):
BIOS:HSWLPTU1.86C.0092.R02.1209220303
Kernel: 3.8.0-12-generic
OS: Ubuntu Raring Ringtail (development branch)

SharkBay(Mobile):
BIOS:HSWLPTU1.86C.0097.R00.1210222040
Kernel: 3.8.0-12-generic
OS: Ubuntu Raring Ringtail (development branch)

SharkBay-ULT:
BIOS: HSWLPTU1.86C.0087.R01.1208151750
CPU: Pre-release Intel MCP processor code named Hasswell M,(2+2) 2 cores,GT2,B0
Chipset :Lynx Point-LP A0(QDBY)
Baseboard: Intel ULT board code named Whitetip Mountain Fab 3.
Kernel: 3.8.0-12-generic
OS: Ubuntu Raring Ringtail (development branch)

Details:
whatever set the resolution by "xrandr -s [0..3]" or by the GUI to set the
resolution, the screen will become garbage screen. And the demsg will appear
"[drm:i915_hangcheck_hung] *ERROR* Hangcheck timer elapsed... GPU hung"

Reproducible: always

Steps to Reproduce:
1.login the system
2.set the resolution

Actual Results:
Garbage screen became.

Reason: It is the issue of xf86-video-intel package, upstream xf86-video-intel hasn't this issue. Both of them have a version of 2.21.4, I compared the source code of ubuntu 13.04 and upstream xf86-video-intel, they are the same. But the configure.ac files are different.

In demsg kernel set vga mode to 800X600 at 225.597737, then GPU hang at 233.865146

Hmm, looks like HSW reintroduced MI_LOAD_SCAN_LINES. Wonderful.

    sna: Haswell reintroduces MI_LOAD_SCAN_LINES

    Better late than never? Interestingly only available from the BLT ring,
    which makes accurate waiting for XVideo (which must use the render ring)
    impossible in the current form - we need to render to a temporary then
    do a vsynced blit in this case.
