Probably requires blacklisting if we haven't done so already.

Comment on attachment 8764762 [details] Bug 1277526 - Blacklist ATI win7 drivers 8.850.0.0 - https://reviewboard.mozilla.org/r/60440/#review57416 Looks good, crashstats also shows a few instances with driver version 8.851.0.0 (worth keeping an eye on).

Should this be disabling all features or only DXVA?

Also, is there a reason to believe that this problem only occurs on a specific driver? I get a whole bunch of similar signatures across a variety of drivers as shown by this search: https://crash-stats.mozilla.com/search/?signature=%40.%2ARtlp.%2Aatium.%2ACreateDeviceLHDDI.%2A&_facets=signature&_facets=adapter_driver_version&_columns=date&_columns=signature&_columns=product&_columns=version&_columns=build_id&_columns=platform#facet-adapter_driver_version

Based on Jeff's insightful comments and some discussion with Anthony, and the fairly low volume of issues, I think I'll just back this out. Alternatives would have been to leave it, but it's only targeting a very small subset of 'RtlpCoalesceFreeBlocks' crashes; or to expand the blacklisting to more driver versions, but it would just remove too much functionality for too many people. My main hope is that bug 1284672 will just fix this class of issues. And Anthony has some more ideas to deal with these crashes, more to come...
