Subject: [mt76x2e] minipcie card is not working

I have a full height production sample mt7612e card that does not work
in either Access Point or Client mode. Monitor mode does not work
either (no packets received/transmitted).

dmesg shows everything to be fine:

[ 5.801993] mt76x2e 0000:2b:00.0: enabling device (0000 -> 0002)

This is on 5.0-rc3.

Tested with a desktop running Ubuntu 18.04 (custom kernel) and an
mvebu device (Turris Omnia) running OpenWrt on kernel 4.14.

I have access to similar device and it does not work for me.

You can check latest mt76 driver https://github.com/openwrt/mt76 ,
some users reported success with mt76x2e problems, but I can
not confirm that with my device.

Do you have Mediatek driver for it (i.e. received driver on associated
CD with the device) or know about such driver. If so, does it work?

Thanks
Stanislaw

Don't have another driver.

I also noticed mt76 starts failing after suspend with this device.
I've blacklisted it for now.
