I have now updated the checksum on my chip and now it seems to work fine. No error messages under boot etc.
Here are som log data:

I dont have any equipment to measure output power so I don't know if I actually got 27dbm tx power.
Anyone know a good way of testing tx power?
Before the eeprom mod I got an error message when I tried to do a "iwconfig wlan1 txpower <pow>" using a pow greater then 20.
Now I can set it to everything above 20 without any error messages.
I can also go beyond 27 if I want but I guess the awus036nha have a max tx set to 27?
