So, your tree is not strictly renesas-drivers-2015-10-13-v4.3-rc5?

:/ Let me know if I can send you debug output.

That one also probes for me... I only disabled DHCP and added my
initramfs. I patched the fbdev build error out and changed Lager dts to
use i2c-rcar (instead of i2c-sh_mobile).
Can you enable CONFIG_I2C_DEBUG_CORE in the config, apply this patch,
and send me the trace output and bootlog?
Thanks,
