Hi, I have been experimenting alot with two wifi cards (MT7925 and QCNFA765), different key-m => key-e passive converters. I get the linux kernel to boot, but it always hangs and reboot after 1s. My guess (as a pure sw engineer) is that when the M2 port gets power, the card browns out. Anyone succeeded with this interesting experiment.
