I tried all ubuntu 14.04 LTS kernels from 3.13 over 3.16, 3.19 to 4.2 and got freezes with all of them except for 3.13. All which produced freezes have been tried with all mentioned kernel parameters and verified it with cat /proc/cmdline. Kernel 4.2 + intel_idle.max_cstate=1 froze within 1 day.
We are running almost 200 machines with a identical setup of ubuntu 14.04 + xfce4 + chromium + html5-kiosk web application which includes an ogm video which is played when idle and otherwise some hardware accelerated html5 animations. 50 of the machines were supported by an Celeron J1900, the remains are equiped with older Core 2 Duo / Pentium Dual-Core or Celeron 847 and ~20 AMD E1-2100 or A4-5000. The most stable kernel for us is the default Ubuntu 14.04 kernel 3.13. We're going to buy AMD Kabinis as we dont have any issues there except the higher TDP and higher temperatures in a complete passively cooled system. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1453298 Title: 8086:0f31 Xubuntu freeze once a day To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/1453298/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
