I have the same Chip i.e : http://ark.intel.com/products/89608/Intel-Xeon-Processor-E3-1505M-v5-8M-Cache-2_80-GHz - which seems to be the same architecture as the 6th Gen U and Y processors. (Despite Matthews edit, these do count amongst those effected)

I am currently running a 4.7 kernel on ubuntu 16.10 with some tlp tweaks. So whatever patches were in 4.7 they don't solve the issues for skylake.

P-states sits in c2 or c3 disabling ntel pstates and using acpi with conservative governor I have seen it in c7. But this means you don't get the boost states/higher frequency clocks. i.e 8k - 2.81k hz only when using ACPI without pstates module. The machine runs cool and well when using the acpi module rather than the pstates. i.e with the following kernel line:

pcie_aspm=force intel_pstate=disable drm.vblankoffdelay=1 i915.semaphores=1 i915_enable_rc6=1 i915_enable_fbc=1


I am using HP Zbook studio g3 with latest bios N82 Ver. 01.13 from the first of August. NVME and Sata drives.

I've had some weird issues include sound disappearing from Windows randomly, and squeeling beeps during post after a hard reset due to crash.
