Both times it happened when I was using Firefox doing something as simple as scrolling through my Twitter feed. There was no 'Hangcheck....' error noted in my syslog and I was able to CTRL>ALT>F1 to console both times, log-in and save kern.log and Xorg.0.log before rebooting. I am still running kernel 4.0.0-997-generic #201503310205 SMP Tue Mar 31 02:07:04 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux from here <a href="http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-next/">http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-next/</a> and xf86-video-intel driver version 2.99.917. I've attached the kern.log and Xorg.0.log from the latest lockup.</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> <li>You are the assignee for the bug.</li> </ul> </body> </html>
