(In reply to Paul Menzel from comment #3) > Interesting. What part is responsible for this? AtomBIOS? No, that is completely unrelated to AtomBIOS. The PLL just needs awfully long to settle and booting the firmware doesn't necessary succeed on the first try sometimes. If the later happens this can even take multiple seconds until everything is settled. > Does the UVD hardware need to start up before displaying something on the > screen, or could it be moved to the user space driver? Yes, all blocks must be started correctly for power management to work because we have a lot of interactions between the different blocks of the hardware. > How long does it take on the new hardware? I honestly don't know in detail. On newer hardware you give a single command to the power management uC and it does everything needed in the background.
