After a resume, my CPU on my i7-6560U gets so throttled that it becomes almost unusable, ranging from 90mhz to ~300mhz, which is below the lower limit: $ sudo cpupower frequency-info analyzing CPU 0: driver: intel_pstate CPUs which run at the same hardware frequency: 0 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: Cannot determine or is not supported. hardware limits: 400 MHz - 3.20 GHz available cpufreq governors: performance powersave current policy: frequency should be within 400 MHz and 3.20 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: 265 MHz (asserted by call to hardware) boost state support: Supported: yes Active: yes I found this thread: https://bbs.archlinux.org/viewtopic.php?id=199922, which suggested using "wrmsr -a 0x19a 0x0". This seems to fix it temporarily, but soon immediately it starts happening again: $ while true; do sudo wrmsr -a 0x19a 0x0 && sleep 1 && sudo rdmsr -a 0x19a; sleep 1; done 1c 1c 1c 1c 1e 1e 1e 1e 1a 1a 1a 1a 1c 1c 1c 1c 1e 1e 1e 1e 1a 1a 1a 1a 1c 1c 1c 1c 18 18 18 18 0 0 0 0 0 0 If I run the wrmsr in a tight loop like "$ while true; do sudo wrmsr -a 0x19a 0x0 && sleep .1; done", then my system is ususable. I've also noticed that if I go to my BIOS and disable Speedstep, the problem goes away entirely. However, my CPU is then limited to a max of 2.2Ghz instead of the Turbo speed of 3.1Ghz. There doesn't seem to be anything interesting or related in my dmesg output. My kernel boot params look like this: $ cat arch-drm-nightly.conf title Arch Linux Intel DRM Nightly linux /vmlinuz-linux-drm-intel-nightly initrd /intel-ucode.img initrd /initramfs-linux-drm-intel-nightly.img options rd.luks.uuid=8b6f7696-53e9-405e-aab6-11d58279e278 rd.luks.options=discard rd.lvm.lv=lvm/root rd.lvm.lv=lvm/swap resume=UUID=1134ceaa-868d-467a-ae77-ce50cea4ee0c root=UUID=74e33803-e02a-4bef-846e-90877bd51dce rw net.ifnames=0 I'm on the latest Dell 1.4.10 BIOS. Also, FWIW, I was previously running a drm-intel-nightly that I built in early November, which IIRC, may not have had this problem, but all previous drm-intel-nightly kernels did show this problem. For the 2-3 week period that I ran the early November nightly, I don't recall seeing this issue, but perahps it was just luck.
I experience the same problem (900MHz) with a Dell Latitude E6430 with BIOS A18. $ sudo dmidecode | grep -A3 "BIOS Information" BIOS Information Vendor: Dell Inc.

But anyway the lastest patch for the cpu throttling fix is at https://patchwork.kernel.org/patch/9629003/ would you please help take a try on latest upstream kernel?

@Chen : I believe that pending changes to the intel-pstate CPU frequency scaling driver, proposed by Rafael, I think for kernel 4.14-rc1, will eliminate the ongoing troubles with Clock Modulation and the driver. I'm saying that the issue will no longer exist, and that the intel_pstate CPU frequency scaling driver will respond "properly" to Clock Modulation events. Of course, I'll check when kernel 4.14-rc1 becomes available, or before if I can apply all the patches.

What kernel is this supposed to be included in? I'm on an xps 9360 and still see the cpu stuck at min frequency after resume on 4.14.4...
(In reply to Brandon Watkins from comment #13) > What kernel is this supposed to be included in? I'm on an xps 9360 and still > see the cpu stuck at min frequency after resume on 4.14.4... The patch was dropped... Humm, I have a xps 9360 in hand, could you please provide the dmidecode log on your platform?
dmidecode is below. Unfortunately I'm not able to re-create it reliably, it seems to happen at random on resuming from suspend. All had seemed well for the past few days with kernel 4.14, but earlier today I resumed my machine, noticed everything had slowed to a crawl and cpupower frequency-info showed the frequency stuck between 300-400mhz (below the 400mhz limit). After rebooting, I've tried suspending/resuming multiple times and haven't been able to trigger it again (so far) DMIdecode: # dmidecode 3.0 Getting SMBIOS data from sysfs. SMBIOS 3.0.0 present.

(In reply to Brandon Watkins from comment #13) > What kernel is this supposed to be included in? I'm on an xps 9360 and still > see the cpu stuck at min frequency after resume on 4.14.4... Brandon - I ended up tracking down the issue to trying to charge my phone over usb-c after a resume. See comments here: https://bugzilla.kernel.org/show_bug.cgi?id=90041#c61 Are you, by chance, only seeing the low frequency issue when trying to charge a device via usb-c? Also, I've since gotten rid of my XPS 13 and have moved on to a X1 Carbon. All of my strange hardware issues have disappeared.
at the time I experienced this I had no devices of any sort plugged into the laptop (I was on batter and I had closed the lid with nothing plugged into it, and a few moments later opened it still with nothing plugged in)
I've seen this happen a few more times (but I've never been able to re-create it intentionally). The only commonality I've seen is that whenever it's happened I was resuming from sleep on battery. It usually sees to happen if the laptop was asleep (on battery) for a long period of time (e.g. overnight). I've verified that when it happens, rdmsr -a 0x19a outputs: CPU 0: 1c CPU 1: 1c CPU 2: 1c CPU 3: 1c If I then run wrmsr -a 0x19a 0x0, it changes to: CPU 0: 0 CPU 1: 0 CPU 2: 0 CPU 3: 0 In my case this does fix it (and the issue does not recur until a subsequent suspend/resume) I've also found that just suspending and resuming again will usually fix it as well (again until a subsequent suspend/resume triggers it I tried updating to the latest bios (2.4.2 from November 2017) but it didn't make any difference
