Title:
iwlwifi firmware panic on 4.13, ucode 29.610311.0
To manage
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.

Title:
iwlwifi firmware
I have a similar situation: wifi will randomly disappear. Some bits from
the logs:
Jul 31 09:20:38 bonobo kernel: [162551.133513] iwlwifi :04:00.0: fail to
flush all tx fifo queues Q 5
Jul 31 09:20:38 bonobo kernel: [162551.204513] iwlwifi :04:00.0: Queue 5 is
active on fifo 2 and stuck
Status changed to 'Confirmed' because the bug affects multiple users.
** Changed in: network-manager (Ubuntu)
Status: New => Confirmed
