First of all try if UVD works otherwise. E.g. we raise the clocks for the boot up test (and lower them again after that), but that's actually not necessary most of the time. So get into radeon_uvd_send_upll_ctlreq, just comment out the error return value and pretend everything worked fine. Then check if the following IB test works or not. If that doesn't work the input clocks to the PLL doesn't seem to work and we have a clock routing problem or something like that. If that works the PLL just doesn't likes our parameters and we need to figure out why. Feel free to contact me by mail if you have more questions. Thanks, Christian.
