ODROID-C2 to aarch64 kernel fails to boot

[graysky]

Is it known that the 4.18.x series of aarch64 kernels breaks the ODROID-C2? I tried booting to it but all I get a green screen on the HDMI. The blue LED is pusling in heart beat mode, but the network is not up; that yellow LED is just blinking once every 3 seconds or so.

just updated, and my ODROID-c2 booted fine:
$this->bbcode_second_pass_code('', '[ 0.000000] Linux version 4.18.6-1-ARCH (builduser@leming) (gcc version 8.2.0 (GCC)) #1 SMP Wed Sep 5 21:37:17 MDT 2018

[graysky]

Did you simply run the two commands I did, ie:
$this->bbcode_second_pass_code('', 'pacman -Rs uboot-odroid-c2
pacman -S uboot-odroid-c2-mainline linux-aarch64')

[summers]

I updated uboot several months ago - and it worked. So tonight I just ran $this->bbcode_second_pass_code('', 'pacman -Suy') alas no records on the uboot update. linux update ran as usual ..
