In that bug report I've specifically asked to check whether this happens on snb

https://bugs.freedesktop.org/show_bug.cgi?id=86507#c3

said no. Please be more careful with checking this. Has the fix for hsw also
addressed the snb backtrace "memory manager not clean"? If not please file a
new bug report for that backtrace.

Also this is a different from the one of this bug report, so bisecting is still
possible.
