What does that mean? Does the 3.19 kernel freeze on Braswell at start-up immediately? What happens when the kernel boot parameter intel_idle.max_cstate=1 is specified for this 3. 3.18.x and newer) when used without kernel parameter intel_idle.max_cstate=1 (please do not confuse this with kernel patching). This thread is about (more or less) random freezes of BayTrail (and possibly newer) processors running NEWER kernel revisions (e.g. 3.13.x) do not exhibit the issue for BayTrail processors. If you make such a statement like the one above then please specify for which kernel revision(s) this is true. > N3700 - both chips are perfectly fine without any patching. > I can fully confirm that this issue is _not_ happening on Braswell N3150 and PowerTOP 2.8 Overview Idle stats Frequency stats Device stats Tunables YES: PowerTop( ) and i7z( ) can tell you this. > Is there an easy way to show the current cstate of the system?
