Public bug reported:
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

I had exactly the same problem too on 15.10. Restarting the iwlwifi
kernel module fixed it, but that's not ideal.
My machine is a thinkpad x1 carbon (3rd generation) and device is a
Intel 7265D wifi device.

Sure, it takes about a day for my laptop to hit the error. Will respond
as soon as possible.
Heads up: The bug does appear to have been fixed in the latest version
of the iwlwifi module from master and latest firmware - I upgraded
the 4.4 kernel to the latest version of the modules and signed
I tried to test 4.6, but that version is even *more* unstable than 4.4
the connection drops out consistently every couple minutes or so.
Also, that version still uses the old firmware, so the driver hasn't yet
been upgraded to master of the authors:
** Changed in: linux (Ubuntu)
Statu
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.

More information: It turns out that upgrading to the latest firmware and
driver *still* does not solve the problem, so, not even the upstream
version of the driver itself is aware of this issue.

I'm sorry, I take that last comment back upstream is still working.
I was just using the wrong kernel (4.6).
Upstream driver/firmware on 4.4 is still running OK.

OK, after 3 days, even the most recent firmware still has this bug:
/lib/firmware/iwlwifi-7265D-21.ucode
I'm switching back to the 15.10 firmware which did NOT have this bug and
we'll see if it still crashes: /lib/firmware/iwlwifi-7265D-12.ucode

Alright, a BIOS upgrade didn't help. Still crashes.
More or less it consistently fails after a day or two, but I have
noticed that if I use the wifi continuously for a long work-day, and
never allow it to sleep or never switch to ethernet, the wifi stays
running.
So, the crashes do seem tied to p
