This is what I finally found. FYI,
- Switch to 22.03 - place device on my desk - two 7915e works correctly
- So, next add metal case - reboot device and ifconfig wlan1 stuck again ...
- remove metal case (upper part) and works again
So, seems BPI-R64 metal case did some "electric" issues.
Finally I used some insulating tape and now works correctly.
So, now have BPI-R64 with two MTK7915e which using in my test setup.
