dmesg with Linux 4.6rc1
1. Set automatic display powersaving mode after one minute of user inactivity
in DE settings.
2. Wait one minute.
3. Tablet lockup in the same second when display goes black (established ssh
connection stop reacting, no ping too) but backlight is still 100%.
Reproducible every time.
Intel Z3735G
Linux 4.6rc1 (was also reproducible with 4.4 and 4.5)
Ubuntu Gnome 16.04 Beta x86_64
DEXP Ursus 7W, also reproducible on few other tablets with same board (like
Prestigio Visconte Quad and others).
According to xrandr display connected via DSI.
I wasn't able to get VBIOS dump, getting input/output error.</pre>
