Hi,

My name is Fernando and I'm from Spain.

We're using Intel NUC NUC5CPYH for a project, with lubuntu 14.04.03.

Sometimes (it's something random) when the pc is going to shut down (or rebooted) it gets stuck at the lubuntu dots animation. If we disable the animation, we can see that it remains at the message :
* WILL NOW HALT
[numbers] reboot : Power down

The only way of making them to work again, is to press the power button manually or to unplug and plug them again to the power supply.

There's nothing wrong at the system logs.

We have tried different kernels, different values for Intel Idle Max State, updating Intel 915 and wifi drivers, and we're running out of ideas.

With the same iso, but using previous NUC DN2820FYKH, we didn't have this problem (and we have around 200 nucs of that model working).

This is something too important for us, because our customers are dissapointed as they don't know what to expect each day.

We'll have to try to update the BIOS, but this is something difficult, as we have Intel NUCS all around Europe, and to flash BIOS via SSH is something that frightens myself.

Best regards
