Using 4.4-rc4 and today's wireless-testing (master-2015-12-10), and
the latest firmware on linux-firmware, my wireless driver runs into a
non-functional loop rambling about "L1 Enabled - LTR Enabled loop".
Reverting back to an older kernel works. I could bisect *if this issue
is not known*, but it may take a while... If you are already
suspicious of a commit lemme know, and I can try to revert. Otherwise
if there's a firmware version that is supposed to work I'm happy to
try that.
Device: Intel dual band wireless AC 7260, REV=0x144
Firmware version: 16.242414.0 (linux-firmware upstream)
I also tried:
Firmware version: 17.246894.0 op_mode iwlmvm (latest on
iwlwifi/linux-firmware.git)
I run into the same issue with this version as well though.

Can you post the good one too?

I had the same issue occasionally when coming out of suspend. Running
4.1 vanilla kernel with 3160 device. The issue also occurred more often
with particular ucode version. Running iwlwifi-3160-10.ucode now and
have not seen the issue pop up since.

So this is interesting..
The opensuse 4.2.4 kernel worked, but I tried my own vanilla 4.2.4
kernel and that didn't work. This lead me to believe this might be a
config issue. I tried the same config on v4.3, v4.2 and v4.2.4 and all
fail with the same issue!
I just tried a base config from opensuse, then localmodconfig, then
'make xenconfig' (which I need) and that worked. I can't debug further
but I think this config might help debug this further:
http://drvbp1.linux-foundation.org/~mcgrof/tmp/config-iwl-fail.txt
So -- my new config works, but I have no idea what fixed it, a config
option obviously. Not sure what though.
