Hi
(Please CC as I am not subscribed to the list)
I'm seeing the following trace on a Lenovo Yoga 2 Pro with an Intel 7260 (rev 6b).
Kernel is 4.5 on using the latest -16 firmware from wireless.wiki.kernel.org. I tried the -17 firmware from git.kernel.org with a
very similar result.
module was loaded with:
options iwlwifi power_save=0 bt_coex_active=0 swcrypto=1
The trace is accompanied by a couple seconds where no data transfer can happen (youtube stutters etc.), but other than that it seems
to resume fine. This happens every 2-15 minutes if I am moving data.
Disabling 11n fixes the problem, but that is not really an viable option.
Please let me know if there is anything I can add to help with the debugging.

I followed the steps you suggested, and am now tracking the bug here:

Can you try:
options iwlmvm power_scheme=1

That can help to know where the problem hides.

Meh... So what happens here is that the firmware is stuck while
transmitting. The driver detects this and as a workaround, resets the
firmware. The detection takes 10 seconds.
The only way to understand what is going on here is to take the
firmware from [1] and to run the steps to collect firmware debug data
from [2]. I recommend you open a bug on bugzilla.
Out of curiosity, did you try to work in DC mode (on battery, not
connected to the power)? A user reported that it helped [3].
