In the log file -

mmc0: Unknown controller version (3). You may experience problems

and a few more error messages. Shutdown hangs for eternity.

wpa_supplicant[1143]: dbus: Failed to construct signal 
wpa_supplicant[1143]: Could not read interface p2p-dev-wlp5s0 flags: No such device 

And then multiple:

INFO: task kworker/u8:0:5 blocked for more than 120 seconds. 

Has anyone else encountered this? Is there a fix / workaround?

The earlier version (17.04) does not have this problem.

This is kernel 4.13.0 issue, fixed in 4.13.5. I had to download compile and install it manually from kernel.org. After that shutdown works fine.

P.S. Thinkpad e570
