This patch should help:

After ~48 hours with this patch, still no apparent issues.

Thanks, this could be optimized for gfx8 a bit if anybody is interested in a typing exercise.

E.g. we only need the tlb flush when "start" or "end" are not 8 entries aligned on gfx8.

I don't have time to test this, but should be trivial to implement.

Christian.
