--- Comment #50 from Topi Pohjolainen <topi.pohjolainen at intel.com> ---
Just as a status update, I've have tried adding unreachable("") exits and
checks for the first dword in the batch buffer in various places according to
possible explanations that I could come up with. So far no luck (well, I have
ruled out some scenarios I suppose). Moreover, the hangs are not that
re-producible, sometimes 3-4 runs is enough but sometimes even 20 rounds just
passes merrily (I've been using x1 Carbon which also heats up pretty badly -
starts to smell).
