I noticed the existence of this error during the boot: "nouveau : 01: 00.0:
bus: MMIO read of FAULT at 612004 [IBUS]".
So I decided to search and found a suggestion to include the following
parameter in the kernel command line "nouveau.modeset = 0". So I decided to
test it and
EDIT: "nouveau.modeset=0" no spaces.

After some tests I discovered that, in my case, the locking is related to
wireless. By disabling the wireless network the problem disappears, it suspends
and returns normally.
So, as a test, I deactivated the power saving, as suggested in the link
Same fault with Dell Inspiron 5557. On resume it takes about 4 seconds
and then the lock screen appears, when trying to unlock it accepts four
to five digits and then hangs completely (nor REISUB works). The only
option is manually power off.

I have the same problem as Desnesn (in #2). Found a workaround that can be
applied while Ubuntu team and the packages developers don't solve the deadlock.
Just install the python-gpgme package for Artful that can be downloaded at
Since network-manager 1.2.6-0ubuntu0.16.04.1 was published in the
xenial-updates repository, I think the status can be set to fixed for
xenial.
code:
apt show network-manager 2>/dev/null | grep -E 'Version|APT-Sources'
Version: 1.2.6-0ubuntu0.16.04.1
APT-Sources: http://archive.ubuntu.com/ubuntu
Also tested network-manager 1.2.6-0ubuntu0.16.04.1 from xenial-proposed for 15
days, and it didn't happen again.
Looks like the error is fixed in that version of network-manager.
