Just updated the Odroid U3 to (patched) Kernel 4.3-rc2, from here: https://github.com/tobiasjakobi/linux-odroid/tree/odroid-4.3.y
Fedora 23 (Twenty Three) Kernel 4.3.0-rc2 on an armv7l (ttySAC1) ................. ]# uname -a Linux rgodroid 4.3.0-rc2 #1 SMP Mon Sep 21 13:38:23 PDT 2015 armv7l armv7l armv7l GNU/Linux
I had tried the ‘standard’ release of 4.3-rc2 from kernel.org, and this booted OK, but the fan control was missing, and the fan ran continuously..
Brief details of changes in kernel.org 4.3-rc2 are here: http://lkml.iu.edu/hypermail/linux/kernel/1509.2/03384.html
