Hmm? What GPU hangs? These patches solve misrendering in GLbenchmark 2.7/TRex on Broadwell, where there were a bunch of stray triangles. When our glBufferSubData path hits a busy buffer, we queue a BLT upload. That blit might be unaligned. I suspect that the new data in the unaligned section never landed (or some data was trashed?), so some vertices end up with bogus data, and some triangles go awry. I'm not aware of any GPU hangs.
