[Solved] Not able to power off

Hi,

I have been using arch for a while now on an old laptop.  I have recently installed it on my new laptop.  I followed the installation guide, I chose grub as my boot loader because it's what I've always used and booted into the main system.

What looked like a warning flashed up in the boot process but I didn't have time to read it.  In hindsight I should have checked journalctl but I forgot.  I created an account then realised I hadn't installed dialog for WiFi. 

I planned to reboot back into the live usb stick and install it and some other things like alsa.  When I typed shutdown -h now it hung for a while then I got messages like

INFO: task kworker/0:1:74 blocked for more than 120 secons.
    Not tainted 4.10.13-1-ARCH #1

Any ideas what I should do?

Re: [Solved] Not able to power off

After a while, I killed power using the power button.  I rebooted into my main system to run journalctl.  Here are the warnings and errors from most recent boot

Thanks.  I'm now able to shutdown properly.  In case anybody finds this, I blacklisted the Nouveau kernel module by changing my /etc/default/grub so the like with the GRUB_CMDLINE_LINUX_DEFAULT now reads this:

GRUB_CMDLINE_LINUX_DEFAULT="quiet modprobe.blacklist=nouveau"

I am however still getting these errors/warnings in my journalctl

Re: [Solved] Not able to power off

Also please always remember to mark threads as [SOLVED] by editing the original post, once you're happy with the resolution.

About the other messages:

ACPI messages are harmless and only recently exposed to shame board vendors (who usually implement acpi by poking around until it works with their random windows version used for testing) - PCCT warning is because this is a relatively new ACPI feature and not supported by your baord.

systemd-tmpfiles messages say "this filesystem doesn't support COW" - it's a false positive

iwlwifi tries various firmwares until one loads, the error does not indicate a problem per se (as long as some firmware is ultimately loaded)

"deprecated" is for developers and means "please adapt to our new API" ;-)

no idea about uvcvideo, do you have an external GPU?
