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.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
