Given Luka Karinja's results, I checked my kernel args to see if something else could account for my results. I found - i915.i915_enable_rc6=1 i915.lvds_downclock=1 i915.semaphores=1 i915.i915_enable_fbc=1.
rc6=1 seems to be known to add instability, perhaps the freq cap offset that. I've stripped the args (except boot, splash, quiet) will be running new tests. Kernel args I've been using the last few weeks on T100CHI. boot=pci,force acpi=force rcutree.rcu_idle_gp_delay=1 libahci.ignore_sss=1 splash quiet acpi_enforce_resources=lax i915.i915_enable_rc6=1 i915.lvds_downclock=1 i915.semaphores=1 i915.i915_enable_fbc=1 drm.vblankoffdelay=1 pcie_aspm=force acpi=force rcutree.rcu_idle_gp_delay=1 libahci.ignore_sss=1 splash quiet acpi_enforce_resources=lax drm.vblankoffdelay=1 pcie_aspm=force -- 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: 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
