Well just that I got it right: The first call runs into an error, but after
issuing the reset and reprogramming everything the second call succeeds?
In this case I would just speculate that somebody (the BIOS?) programmed the
PLL with such incorrect values that it locked up and need a reset to work
properly again.
Can you just reduce the first call to radeon_uvd_send_upll_ctlreq to a warning
and continue? If the second call works we have successfully programmed the PLL
and everything is fine.</pre>
