On random occasion, or with certain wifi loads, iwlwifi panics with the wifi nolonger being wakeable;

Status changed to 'Confirmed' because the bug affects multiple users.

I have a similar situation: wifi will randomly disappear. Some bits from the logs:

And I'm on Ubuntu 18.04. I think I saw it on Ubuntu 17.10 as well, but happens reasonably frequent now, every few days.

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1743489

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

It's very similar to the behaviour described here: https://bbs.archlinux.org/viewtopic.php?id=231159

I also have a Intel(R) Dual Band Wireless AC 7260, REV=0x144.
