Well, that won't be caused by processor microcode, so this bug needs to
be either reassigned to something other than intel-microcode, or closed.

WoL being active or inactive causing issues on shutdown will be
sensitive to:

1. kernel

2. WLAN firmware

3. systemd/udev (if you are using it) OR initscripts/udev (if you are
not using systemd).

Maybe you can track down in /var/log/apt and /var/log/* which packages
were updated between the last time your laptop had been correctly
powered off and when you noticed it broke?

Otherwise, we don't have enough information to track the issue, and we
should close this bug...
