Hello,
I use Enlightenment (enlightenment-0.21.5-1.fc25.x86_64).

After upgrading kernel to 4.11.4-200.fc25.x86_64, I'm unable to execute sudo and to unlock screensaver.

Executing sudo with or w/o any parameter gives me a message:

sudo: effective uid is not 0, is /usr/bin/sudo on a file system with the 'nosuid' option set or an NFS file system without root privileges?

That's strange for me.
I have tried to ssh root@localhost, then "su - user" to decrease privileges.
Sudo works properly in the case, but continuously not working while exetuting from Enlightenment+Konsole shell.

Also, I'm unable to unlock Enlightenment from screensaver even with simpliest password, but I do not know which logs should I collect for that case.

All these cases are related to Kernel upgraded from 4.10 to 4.11.
Rebooting back to kernel 4.10.16-200.fc25.x86_64 fixes all these issues.

Sudo works properly when using KDE and Kernel 4.11.

Multiple reboots gives 100% reproducible results.

Is there a way to fix the system to work properly under Kernel 4.11 and Enlightenment?

I'm open to do any investigations on my workstation.

Thanks.
