            Bug ID: 77951
           Summary: "intel_pstate: Set turbo VID for BayTrail" causes
                    stall on Intel NUC DN2820FYKH
           Product: Power Management
           Version: 2.5
    Kernel Version: 3.15
          Hardware: x86-64
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: cpufreq
          Assignee: [email protected]
          Reporter: [email protected]
        Regression: No

The hardware:
DN2820FYKH (BIOS version:0028)


The symptom:
The kernel stalls at "Loading, please wait" or sometimes at the the next line
where udevd is launched.


I did a bisect which identified the commit
21855ff5bcbdd075e1c99772827a84912ab083dd "intel_pstate: Set turbo VID for
BayTrail" as the cause.

I also confirmed it by reverting the commit on v3.15 which fixed the stall.
