Tom,

It turns out that your GPU hang was due to a bug in our MRT support. It should be fixed on master by:

commit 172bb92db1a3c317867d9cfec6f15c09c37a0f6c

    i965: Only set Last Render Target Select on the last FB write.

    Fixes GPU hangs in OilRush, Trine, and Amnesia: The Dark Descent,
    which all use MRT (multiple render targets).

    NOTE: This is a candidate for release branches.

That patch is also on the 8.0 branch as of today. Your apitrace file no longer hangs my system. Could you confirm?

Thanks! Sorry this took so long.
