gpu crash dump

I am trying to do high FPS image encoding into webp (VP8) format using libva on
i965 driver, I am trying to avoid having to initialize and deinitialize libva
for every frame to achieve best possible performance, after a few successfuly
encoded frames I am getting GPU HANG : ecode 9:1:0xfffffffe - GPU crash dump
attached
GPU hang does not occur when initializing and deinitializing for every x frame
encode.

Please advise.
