A patch[1] is composed partly from the RT3573 source code patched by ashaffer, from Andreas work, some of the ideas are from the beagleboard community, and some of my. :)
Debug(trace) is turned off.
Device now works more or less OK but slow, max. 10 Mbit, although connectable is only within the "N" & "N/G" modes.
What is important is the system no longer crashes, and disconnection are rare.
Generally better than before.
Tested with kernels:
3.15.10-200.fc20.x86_64
3.16.1-301.fc21.x86_64
3.17.0-0.rc2.git0.1.fc22.x86_64
and with debug kernel:
3.17.0-0.rc2.git1.1.fc22.x86_64
dmesg:
...
mt7601Usta: module verification failed: signature and/or required key missing - tainting kernel
