In the log file - 

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

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

nouveau 0000:01:00.0: bus: MMIO read of 00000000 FAULT at 022554 
[ IBUS ] sd 2:0:0:0: 
[sda] No Caching mode page found     
wpa_supplicant[1143]: dbus: wpa_dbus_get_object_properties: failed to get object properties: (none) none 
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.

  • Could you please provide the logs you saw, as well as a more detailed explanation of the problem? – Nonny Moose Oct 20 '17 at 21:06
  • The problem mainly manifests in hanged shutdowns. Additional log entries:

    nouveau 0000:01:00.0: bus: MMIO read of 00000000 FAULT at 022554 [ IBUS ] sd 2:0:0:0: [sda] No Caching mode page found

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
