Looking at the file Christopher linked to earlier states this: "Organization: Intel Open Source Technology Center
The Baytrail SOC has a built-in feature to demote core and module C6 to shallower idle states. Based on work in the Android copy of the Linux kernel tree, this feature was disabled starting in Linux-3.17-rc1:" ...So that looks promising as that is the exact thing we found in this bug report early on. Kernel 3.17 was the kernel i started getting huge freezes on, and when originally we were going through the bisecting rc1 was the one we had stopped at. So cool to see someone else has confirmed that portion. ...now to see if i can figure all this stuff Christopher wants me to do. Christopher i'm going to be honest and say that your really bad at explaining stuff since you just post links that are somewhat technical. I think i can figure it out, but my brain doesn't compute as fast as it used to. Right now i gather that i need to just edit my grub on bootup and test the intel_idle.max_cstate=1 parameter. (not sure if that will remain on future bootups or if that is persistent and will remain). Then if that works well i test the debug patch and script. (not sure if i need to disable intel_idle.max_cstate=1 when i do this). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1575467 Title: [Dell Inspiron 3451] WARNING: CPU: 1 PID: 1297 at /build/linux-lts- utopic-vy2yyy/linux-lts- utopic-3.16.0/drivers/gpu/drm/i915/intel_display.c:1743 vlv_wait_port_ready+0x126/0x170 [i915]() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1575467/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
