Hi folks,

I haven't followed the previous discussion on this matter, so one
question: Is this a coreboot issue? If this noise doesn't occur with
the vendor firmware, has anybody checked if coreboot uses the same
power management timing settings? (e.g. C4-TIMING_CNT, see [1], there
might be more such settings not mentioned in the public datasheet)
