However, trying to workaround it like results in an error:
sudo wpa_cli resume
Failed to connect to non-global ctrl_ifname: (nil) error: No such file
or directory.
This bug is the same as, or similar to:
No wifi
I've run into this with my x220 which was recently upgraded to Xenial as
well. It is not consistent; it happens at maybe 1 out of 3
suspend/resume cycles.
Removing and reinserting the iwldvm module also fixes the issue, but

Which Ubuntu release is that, wily or xenial? (Please use apport to file
bugs).
/lib/systemd/system-sleep/wpasupplicant is a nasty hack/workaround

Mathieu, did you see this before? Any hints what to do here?
@Haw: Can you please include the full logs before and after suspend? The
timestamps indicate that this was only for the suspend part. Thanks!
