Hi,
I kave some problems with my new rock64 sbc (4Go, Ubuntu on 16Go eMMC, wifi). Here they are:
1: generally the first starts crash, with the red led on. After few restarts (or/and time of use), i have the impression that the board works better. Perhaps that a required working temperature is not reached before a given time (?)
2: after the start-up, the board always give the error: Fail to apply network settings. You light not able to connect to bluetooth network via this machine. Exception: org.freedesktop.DBus.Error.Spawn.ExecFailed: fait to execute program org.blueman.Mechanism: Permission denied
3 the highligthing of the menus items are very very slow to follow the mouse cursor
4 taking a screenshot does not work
that's all for now. Someone can help
Regards
Pascal

I tested 'mele F10' on rock64 with official Android TV 0.3.13 image and it is NOT working. Can anybody confirm this?
Tried connecting dongle on usb2 and usb3 port and using power supply 3A. Still not worked. This classic airmouse works on every other board since the age of cubieboard.

| Compiling android kernel |

Hey guys!
I need to change a few lines of code in the android kernel. I'm using this build but can't seem to find the kernel sources used to compile it. I tried to compile these sources up to the 3.10.104 merge tag but I get a lot of compilation errors. What gcc version should I be using? And once I compile the kernel how do I flash it to the rock64? Do I just use the compiled Image file as the kernel.img in AndroidTool or do I have to package it somehow?
Thanks!

**Server setup**
Rock 64 4GB
Xenial minimal: Ubuntu 16.04.4 LTS (GNU/Linux 4.4.126-rockchip-ayufan-227 aarch64)
**Problem**
I recently did a full "sudo apt update && sudo apt full-upgrade" (not sure it's related), and had a lot problems since.
My "load average" and core use is recently very high. If I examine using htop, I notice a lot of it is taken up by sabnzbd (which I'm running in a docker container). I used to have a "load average" in use of 2-3, max 4-5 and now it easily gets up to 8-9 when downloading two files.
I also had a bunch of system crashes, which I can't seem to replicate, which I'm now assuming was due to high load.
I'm not sure it's related, but I checked out the kern.log and syslog and saw nothing out of the ordinary, except for an incredible amount of these errors (or similar):
Code: uses deprecated CP15 Barrier instruction at 0xf6646c30
cp15barrier_handler: 416 callbacks suppressed
