Oh, wow! patch in attachment 89886 [details] [review] seems to fix this issue for me. Today is thanksgiving here in the USA. I am thankful for open source radeon drivers. I am thankful for your efforts, Alex Deucher. This would confirm that it is a bogus BIOS setting where the bios reports 384, but it is actually only 256. I tried something similar on my own earlier, but I did not understand the memory layout well enough to know to adjust the base address. Thank you for trying yet again to fix this, Alex. I am testing now. Anyone else on this bug able to test this proposed fix?
