Problem booting with 3.16 and custom build

[Dashie]

Hi all,

Still me working with my kirkwood board, i can get a 3.12 kernel from Debian working, but not with 3.16.

With 3.16 the USB (which i have an usb-key with the rootfs) doesn’t seems to be detected at all (no mentions of /usb/ in dmesg), no problem with 3.12.
Also don’t see any related USB changes between config-3.12 and 3.16 diffs which can cause that.

If i build a custom kernel (with config-3.12-1-kirkwood or even the one from 3.16), ARCH=arm and toolchain gcc-linaro-4.9-2014.11-x86_64_arm-linux-gnueabihf the boot from U-Boot
fails with:

=========
Starting kernel ...

Any ideas for theses problems ?
At least getting the recent 3.16 booting properly will permit me to build and load modules easily.

Thanks.
