[Bug 1577957] Re: Intel 7265D wifi firmware crashes on a Lenovo x1 carbon (3rd generation)
I confirmed this *again* in a much easier way, by using the RF-toggle
switch to cycle the wifi manually on the laptop.
On 4.6, this makes the firmware crash (same error as above).
With the upgraded iwlwifi module and upgraded firmware, the error goes
away.

Title:
Intel 7265D wifi firmware crashes on a Lenovo x1 carbon (3rd
generation)
Status in linux package in Ubuntu:
Confirmed
Bug description:
The stock firmware for this device /lib/firmware/iwlwifi-
7265D-16.ucode is crashing.
Downloading the latest firmware (/lib/firmware/iwlwifi-7265D-21.ucode)
isn't supported by the existing iwlwifi driver, and so the driver
likely needs to be upgraded (or downgraded as well
(https://git.kernel.org/cgit/linux/kernel/git/iwlwifi/backport-
iwlwifi.git/?h=release/LinuxCore18).
I can also confirm that wifi *did* work successfully on 15.10 before
upgrading to 16.04, although the kernel module required frequent
restarts due to this bug:

A detailed message about the firmware crash is located in the attachment from dmesg output.
Thanks.
