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.
