Which is the espected result if you don't setup the clocks :)

In this case the UVD block runs with the default 100Mhz instead of the desired
400,500,900 or whatever the power tables say we should programm it to. At least
we now knew that the input frequency works well.

Now take a look at si_set_uvd_clocks in si.c. Especially try to figure out if
the first or the second call to radeon_uvd_send_upll_ctlreq fails.

Additional to that please install radeontool and get me the content of the
CG_UPLL_* registers. E.g. I need the output of:

radeontool regmatch 0x634
radeontool regmatch 0x638
radeontool regmatch 0x63c
radeontool regmatch 0x644
radeontool regmatch 0x648
radeontool regmatch 0x650

Thanks,
Christian.
