on bug 93649
from Marek Olšák
Does this fix the hangs? https://cgit.freedesktop.org/mesa/mesa/commit/?id=d4d9ec55c589156df4edc227a86b4a8c41048d58 It changes the HTILE (HyperZ) allocation function to r600_aligned_buffer_create. Without that, the hardware can hang on big GPUs (Tahiti/Pitcairn/Hawaii/Tonga/etc), but not APUs or small GPUs. The hang happens when TTM decides to move HTILE to a different location with an unaligned physical address (which is pretty random). The hardware tries to access the unaligned address and boom.
