I have system freezes on ASRock Q1900-ITX with a kernel 3.19.31-generic on an Ubuntu distro. I upgraded to kernel 4.2.0-16-generic last month and recently to 4.2.0-18-generic. The system freezes got worse (less than 10 min watching videos).

I disabled hardware acceleration in all software with this option, like in my browsers. Further I edited the file /etc/default/acpi-support: I disabled suspend/hibernate handling in acpi-support by changing the line "SUSPEND_METHODS="dbus-pm dbus-hal pm-utils" to "SUSPEND_METHODS="none".

I don't get any freezes anymore, now for 24h for both kernels 3.19.31-generic and 4.2.0-18-generic with a lot of video playing. I didn't tested on kernel 4.2.0-16-generic.

I tested disabling hardware acceleration without changing the acpi-support file. And I tested disabling suspend/hibernate handling with hardware acceleration. In both cases I still got freezes but it seems less frequent. I needed both options disabled to get rid of all the freezes.
