Ok so this is the strangest thing that happened to me ever with Arch.
I was using my laptop normally and suddenly NetworkManager crashed. I tried to relaunch it but everytime I run a command with sudo it hangs...
So for example I can run 'ls' but not 'sudo ls'. 'ifconfig' hangs also even without sudo, systemctl also....
After a reboot it's the same, I plugged an ethernet cable and still don't have any connection.
Btw I didn't update this system since few weeks/months. It's on kernel 4.11.9-1
This is the only relevant log I find, seems to be related to iwlwifi. But even if let's say my wifi card burned or something like that (since I didn't update or anything this kinda makes sense to me) it doesn't explain why I cannot run certain commands anymore...

If you have any idea which other log could be relevant I'll be happy to add it
Thank you

What is the specific output when you run sudo ls ? How about sudo su ?
Can you log in as root?

sudo su
no output, hanging
sudo ls
no output, hanging
su
ask for password and I can login but if I run ifconfig after it hangs, ls works there
very strange...
I've tried using different terminals also

Why are you running a rotten kernel?
Try to blacklist iwlwifi (https://wiki.archlinux.org/index.php/Kernel_modules#Blacklisting - use the "install ... /bin/false" method)
You probably run into PAM issues because of failing host resolution or so. Paste a complete journal for better insight.

Doesn't that dmsg just mean that the driver isn't signed/ hasn't been integrated into the kernel? Or uses a different license than the kernel (proprietary modules)?

It does especially say "4.11.9-1-ARCH", there's at least an out of tree module being loaded (could be iwlwifi or something different)
"G" indicates all modules should have a GPL license (or lie ;-)

Ah! I see what you're saying now. I misunderstood what you meant by "Why are you running a rotten kernel?". I thought you were asking why he was running a tainted kernel.
