[SOLVED]iwlwifi chaos, fail to flush all queues

Question

Having this weird problem of iwlwifi crashing, mostly happens after waking up from sleep mode or when the battery reaches 50%.
It is so random but it starts with, 'Error sending _CMD, time out after 2000ms'.
Immediately after, it tells you, 'fail to flush all tx fifo queues'
Goes on, until you see, 'Restarting adapter queue is full'.
Systemd is configured to reload iwlwifi after suspend.
Tried on/off for pcie_aspm, iwlwifi options like wd_disable, 11n_disable but ran out of any other ideas.
Did anyone else notice anything same with Intel's wireless drivers?

Answer 1

I had a similar problem with my: Intel Corporation Centrino Wireless-N 1030 [Rainbow Peak] (rev 34) wireless card in a Dell vostro v131.
A lot of : "fail to flush all tx fifo queues" and connect/disconnect from my router,
I tried a lot of different solutions with the driver options. One looks to work for me.
options iwlwifi bt_coex_active=0
(in a /etc/modprobe.d/iwlwifi.conf)
No need to disable 802.11n, it's stable... i'm able to watch a movie streaming (via pulseaudia) to a ΅sound machine" without problem.
Cheers
