[Stuart Bishop <1435728@xxxxxxxxxxxxxxxxxx>]

The trigger was not the kernel version. The trigger is upstart or
systemd. The laptop reliably reconnects to wifi after resume if I have
booted using the 'upstart' option in the grub advanced boot menu. If I
have booted using the default grub selection, the laptop reliably fails
to reconnect to wifi after resume.

I have been working in 'upstart' mode most of the time recently, for
unrelated compatibility issues, which is why I had been unable to
reproduce this for the last week.

I will attach kern.log logs, showing a fresh boot in upstart mode
followed by three successful suspend/resumes. And kern.log logs, showing
a fresh boot in systemd mode followed by three failed suspend/resumes
(and rmmod, modprobe in between).
