[Voyage-linux] APU-2

[Jordi Ferrer]

Hi,

I've been running voyage 0.9.5 & kernel 3.14.12 on PCEngines APU board 
for a long time
without any problem.
Last week I got my first APU-2 board and I migrated my system to it.
I experienced system freezings at the end of the boot process some 
times, and many
kernel (3.14.12) crashes during the reboot and halt,

I updated my voyage 0.9.5 to kernel 4.1.6 version. Now there is NO 
crashes during reboot and halt
but I still have freezings at the end of the boot process few times.

Is it going to help migrating to voyage 0.10.0? does anyone have long 
experience using APU-2 and
any version of voyage linux and kernel?

PD: I'm running on a mSATA drive.

BTW: I've created a patch for the kernel 4.1.6 to use the 3 front LEDs 
on top of a GPIO driver (also included)
for the front LEDs and the front PUSH BUTTON, which replaces the 
existing LED driver in the 4.1.6 that, I think, only
works for the 3 LEDs.
