I decided to upload the files to the web instead of attaching them to
the email since they are quite large.

The dmesg may not reveal much, but if I blacklist acer-wmi for booting
and then load it later manually, this is what appears
in /var/log/messages:

kernel: [ 4795.867540] acer-wmi: Acer Laptop ACPI-WMI Extras
NetworkManager[914]: <info> found WiFi radio killswitch rfkill7 (at /sys/devices/platform/acer-wmi/rfkill/rfkill7) (driver acer-wmi)
NetworkManager[914]: <info> WiFi now disabled by radio killswitch

Then, if I unload acer-wmi:

kernel: [ 4852.875590] acer-wmi: Acer Laptop WMI Extras unloaded
NetworkManager[914]: <info> radio
killswitch /sys/devices/platform/acer-wmi/rfkill/rfkill7 disappeared
NetworkManager[914]: <info> WiFi now enabled by radio killswitch
NetworkManager[914]: <info> (wlan0): bringing up device.
kernel: [ 4852.905625] wmi: Mapper unloaded
