I did a few more tests. On my system, the combination of a realtime (lowlatency) kernel and certain tlp settings fixed the random crash. Although the side effect was the machine can get very hot because CPU threads cannot be turned off. Processor: Intel® Core™ i7-6567U Graphics: Intel® Iris Graphics 550 (Skylake GT3e) Linux kernel: 4.11.12-1-rt16-MANJARO TLP modified settings (/etc/default/tlp): SCHED_POWERSAVE_ON_AC=0 ENERGY_PERF_POLICY_ON_AC=normal Note: this combination also solved the intel 8265 bluetooth random disconnection and reconnection failure on this machine. All these tests were carried out on Manjaro, but I did suffered similar problem when I was testing Ubuntu 17.10. I hope my information can be helpful. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to libdrm in Ubuntu. https://bugs.launchpad.net/bugs/1535048 Title: i915 driver seems to cause system crash at random To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libdrm/+bug/1535048/+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
