Hi,
I have described deadlocks with kernel 4.1.6 in "Re: Voyage-Linux - APU2
- SD Card" on 08/31/2016 06:01 PM. I have fixed it by using kernel
linux-image-4.6.0-0.bpo.1-amd64 (or current
linux-image-4.7.0-0.bpo.1-amd64-unsigned) from jessie backports.

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.
