--- Comment #44 from Alex Deucher agd5f@yahoo.com --- Created attachment 86296 --> https://bugs.freedesktop.org/attachment.cgi?id=86296&action=edit patch 1/2
This patch set works around the issue by limiting the sclk and mclk to the highest levels listed in the clk/voltage dependency tables. I'll need to dig a bit more internally to try and figure out how to handle these clks properly.
