Aha, you have a SuperSavage. Unfortunately it seems like vertex DMA locks up these cards. Other SuperSavage users reported the same. I don't know why and I can't debug the problem because I don't have a SuperSavage to test (and neither has Alex :( ). The only way seems to be to disable vertex DMA. There is a driconf option for that named enable_vdma. It's on by default. Set it to false.
I had to work around a hardware bug on Savage IX too. Take a look at drm/shared-core/savage_bci.c (function dispatch_dma_prim) for the details. Maybe you can try if the same helps on your SuperSavage?
