I have a major problem with R6040 driver, it is broken in TC4!
In 3.8 it works normally... I've attached complete dmesg log, here is the end of it:
mii_bus 0 failed to register
r6040 0000:00:08.0: failed to register MII bus
r6040: probe of 0000:00:08.0 failed with error -22
I am using DMP eBOX-3300 mini-pc (with Vortex86 SoC) and I really beg you to fix this issue!
