Created attachment 105745 [details] Workaround Async DMA linear to tiled copies are causing GPU hangs in some cases. On Cape Verde, I can easily triggers this as described in [1]. The game Brutal Legend also triggers similar hangs when it streams assets while gameplay. Disabling usage of this function and using the resource_copy_region fallback instead fixes all hangs. The attached patch does that. [1] https://bugs.freedesktop.org/show_bug.cgi?id=79980#c124
