Hello everyone,
I'm just trying to get my kernel built for my Odroid U3, but no matter whether
I use 4.0.x or the latest code from arm-soc repository 4.1.0-rc3, it ends at
this message during boot:

The error messages during uboot loading just appear because there is something
missing in it's RC, but don't think it is the reason, because a old build
(3.19.x) just boots.
Sadly my serial output does not give better error messages, so I'm asking
here, because google'ing around didn't point me to any solutions.
Do you have any hints why that happens? My .config can be found here -
http://pastebin.com/qRLmtmmt . Is there a way to get early error messages
during boot?
Please goto 'Kernel hacking' page and enable 'Kernel low-level debugging
functions' with 'Use Samsung S3C UART 1 for low-level debug' and then
also enable 'Early printk'. Then add 'earlyprintk' to your kernel cmd
line. I hope you are using the exynos4412-odroidu3.dtb compiled from the
same kernel tree as zImage.
Best regards
