At last,I found the answer.
I used libdrm-2.4.27 which does not support IVYBRIDGE_S_GT2. Using the latest libdrm-2.4.34 to solve this problem.
VAAPI still complains "cannot open i965_drv_video.so",I find the latest intel-driver-1.0.17 doesn't support IVYBRIDGE_S_GT2 .
Add #define PCI_CHIP_IVYBRIDGE_S_GT2 016a(line 175)and devid==PCI_CHIP_IVYBRIDGE_S_GT2 (line 205) in intel-driver-1.0.17/src/intel_driver.h,
Now it works!

   System environment:

libva:1.0.15

Bug description:
In order to use VAAPI to accelerate decoding in Ivybridge ,I installed  xf86-video-intel 2.19 which supports
PCI_DEVICE_ID_INTEL_IVYBRIDGE_S_GT2_IG,and restarted system.
System stoped with blank screen,after loaded intel_drv.so
Xorg.0.log is in the attachment.

By the way,it seems little information with VAAPI except source code ,
could you send me some documents about VAAPI or intel graphic card decoding?

thank you very much !
