Atom has new (lower) power states, with wakeup sequences that are very different from previous PC platforms. I don't know exact details, unfortunately. :\ > Also, PhoenixBIOS seems to play part in the problem. I do know that the power sequencing is not really part of the Intel reference platform, but rather it will be solved in a microcontroller or embedded controller by the systems designer. The BIOS needs to support this properly. This is all new stuff on PCs. It is very possible that there are BIOS bugs. If you send an email to the coreboot mailing list, it is possible that someone there has an Atom system running coreboot and would be willing to help test if given a card. If so, they are also very knowledgeable about the lowlevel details. //Peter _______________________________________________ Bcm43xx-dev mailing list [email protected] https://lists.berlios.de/mailman/listinfo/bcm43xx-dev
