--- Comment #42 from Ben Widawsky <ben at bwidawsk.net> ---
Just to recap on the status:
No patches: 2.5s to BSD hang
intel-vaapi: ??s to mesa hang
intel-vaapi + mesa patch: 3-10m to mesa hang
intel-vappi + mesa patch + kernel patch: 20m to mesa hang
intel-vaapi + mesa + kernel + blt only: being tested

While it could be a false correlation, the patches so far seem to have improved
the situation. The SNA fix seems to be in master as well, but Knut wasn't able
to test that in the limited time he had, so we went with blt only instead.

Expecting an update from Knut on the blt only DDX. Chris, will blit only never
emit 3d state?
