I guess we just have many different types of hangs then... ring_gfx hangs are more mysterious than sdma0/1 hangs it seems, since there is no "universal" workaround for them. nodma works for stopping global sdma-type hangs for me, nongg works for stopping the citra-related hang of ring_gfx type, but none of those 2 variables work for stopping Starcraft II and RoTR ring_gfx-type hangs for me, so it's really really confusing.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
