I guess this issue is gone once you remove peaq-wmi? $ sudo modprobe -r peaq-wmi

Fail to shutdown properly. Status in network-manager package in Ubuntu: New Bug description: I am not sure that this is a network-manager fault... just because it causes troubles on shutdown (see shutdown section below). Network manager is fine while system is running... PROBLEMS I used Ubuntu Mate 17.04 and was happy. After 17.10 release I upgraded system with Software Updater tool. Upgrade was successful. But after a day or so I noticed some problems with UI: - When try to select a group of object on desktop or in the caja file manager the selection is gone in about a second. - Some popups (my translator plugin in firefox) was closed after appearing. - When press and hold a key (arrow key to navigate in text or just a symbol) the input was interrupted in about a second, like I release the button. (For different desktops UI troubles are different, but problem with pressing and holding key is common for KDE 5, Gnome 3 and Mate). Then I noticed "^@" (without quotes) sequence appears in pure terminal (Ctrl + Alt + F[1-8]) a bit more frequently than a second. Probably it brakes UI. I reinstalled Ubuntu Mate 17.10 from scratch, but the problem remains. I also tried Kubuntu 17.10 and now Ubuntu 17.10 (with Gnome 3) with persistent install but problem is still here. More the problem is present when I boot from usb stick. But I have no troubles on Ubuntu 17.04 Mate and Windows 10 WHAT I TRIED - Update BIOS to the latest version - Update Intel microcode - Uncheck "Use Intel Microcode" from Device Manager - Switch between proprietary and Xorg drivers for NVidia - Unmount and spin off HDD - Add wi-fi kernel modules (ath, ath10k_core, ath10k_pci) into blacklist (seems that it had no effect, they were loaded) - Install all updates SHUTDOWN PROBLEM System cannot shutdown properly. It can hung (or maybe just waits and doesn't show any logs or shows only a few lines - once it happens) or, in most cases, I see: [ *** ] A stop job is running for Network Manager (<waiting time>/<max time to wait>) OR [ *** ] A stop job is running for WPA supplicant (<waiting time>/<max time to wait>) And later this INFO task kworker/<info> blocked for more than 120 seconds is added to the line Where <info> could be different, for example: u8:2:169 or 0:1:33 If I wait about 6 or so minutes I finally can see: Reached target Shutdown But the laptop is still on and I have have to hold power button a few seconds to halt it. (for more information see attached photo-screenshots HARDWARE I have used Lenovo ideapad 700-15ISK all the time without hardware modifications. P.S. Feel free to ping me if you need additional info. Also I always can experiment from live usb stick.
