Description of problem: I plugged in an ethernet cable. My bios is set to disable the wireless hardware in the presence of an ethernet connection so the wifi turned off.

This looks like follow up of 919176, or happened after system reboot ?
This did happen several days after bug 919176 and the system had been powered off several times since then, it did not happen immediately after rebooting though.
I suspect this can be also similar issue as on previous bug report, i.e. iwlwifi firmware problem, please attach dmesg.
Created attachment 709565 [details] dmesg file for the incident
This really looks similarly like bug 919176, two microcode errors and then WARNING. Though warning is different, it is a consequence of iwlwifi firmware problems. *** This bug has been marked as a duplicate of bug 919176 ***
