The mPCIe power-on, reset logic is not up to spec. The PCIE RSET is 185 MS before 3.3v is available. This reset should be after and not before power.
This is preventing from mPCIe cards from functioning correctly when power is first applied. the system function after reboot.
Intel should make a change to power on first, than reset.
BIOS version 0025 3/3/2014
i have attached the actual power on scope sequence showing the power comes on 185ms after the reset.
Please advise.
