Dell Precision M3800 Wifi Fails to start on boot sometimes

Note: I posted this in the laptop forum and haven't gotten any replies.  So I am posting it here as I don't see how to move it.

I have a Dell Precision M3800 Laptop and most of the time when it boots, the loading the iwlwifi module fails.  If I reload the module after a failed booting it always works.

I can't figure out why it does this.  The main error appears to be

Apr 14 21:26:13 leda.scit.us kernel: iwlwifi 0000:06:00.0: Failed to run INIT ucode: -110

Searching for this error hasn't produced a successful, permanent fix.

Reloading Module Fixes it

Opening up a terminal and issue the following command always fixes the wifi.

# sudo rmmod iwlmvm iwlwifi && sudo modprobe iwlwifi
