Ok, I tried 3.18-rc1 (with dt appended to the zImage) and this should be the logs from that attempt (on PC).

Well it works My goal is to get nfsroot to work, and then I can play with bluetooth, userland and power management. For now, power consumption is not important, as I'm unable to boot useful system. (I could boot from MMC, but that's too cumbersome to use due to lack of space, hard communication, and constant fiddling with device cover).
