Description of problem: Fedora 23 won't boot on new Skylake processors. I've tested with install DVD and also with upgraded kernel. The machine hang's during boot on intel_pstate driver. The only way to get around is to turn off with intel_pstate=no_hwp,but this turns off power saving. Version-Release number of selected component (if applicable): [rsmol@yoga-laptop ~]$ cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 78 model name : Intel(R) Core(TM) i5-6200U CPU @ 2.30GHz stepping : 3 microcode : 0x74 cpu MHz : 746.718 cache size : 3072 KB kernel-4.3.5-300.fc23.x86_64 It is Lenovo Yoga 260 HW. How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Blank screen. Expected results: Normal boot. Additional info:
Skylake support is incomplete in the 4.3.y kernel. You might have better luck with the 4.4.y kernel, which F23 is being rebased to this week.
Hi, I've tested against kernel-4.5.0-0.rc4.git2.2.fc24.x86_64 it is the same issue, can I somehow test something or help? sudo dnf config-manager --add-repo=http://alt.fedoraproject.org/pub/alt/rawhide-kernel-nodebug/fedora-rawhide-kernel-nodebug.repo the last message on screen is: intel pstate hwp
Hi,currently on 4.5.0-1.fc25.x86_64, the issue is still here. Does it mean Skylake will not be supported in F24? The last message I see intel_pstate: HWP enabled and then nothing I have to press power button for 4 seconds.
Hello, today on 4.4.6-301.fc23.x86_64, still same issue. Is there any test I can provide to help this to get fixed? I've also tested F24 alpha, it had same issue ;(
it seems I might be running into this bug. https://bugzilla.kernel.org/show_bug.cgi?id=110941
patch from that bug works! I've followed this guide. https://www.reddit.com/r/thinkpad/comments/4c6q6w/fixing_intel_pstateno_hwp_issue_on_fedora_23_guide/ Please consider to include that patch in the kernel and close this bug. Thank you
Pushed to repositories. It should show up in a build next week.
