The symptom is that the pstate driver can scale the frequency up, but

Intel 8260 WiFi cards currently aren't usable on 14.04.3 (with lts-vivid

I put 3.13.0-32.56 with the iwlwifi-7260-8.ucode through around 32 hours

@jasauders: you'll need to download iwlwifi-7260-ucode-22.24.8.0.tgz
from here:

Extract the tarball, then copy iwlwifi-7260-8.ucode into /lib/firmware,
then reboot, check dmesg to make sure it loaded the correct version:
$ dmesg | grep iwlwifi
Seth, I noticed that the linux-firmware package in proposed (1.127.3)
doesn't have the 7260 -8 firmware, but does have the 3160 -8 firmware?
Is this intentional?

Public bug reported:
The current linux-firmware package in proposed (1.127.3) added the -8
firmware for the Intel 3160, but not for Intel 7260.
This seems like it was perhaps a mistake, as the -9 firmware has been
added for both.

Seth,
Progress report from testing your patched 3.13.0-27 build... I made it
through almost 5 days of continuous use without a disconnect. Even
though I did eventually get a disconnect, it seems to happen far less
frequently with the -8 firmware when combined with the disabled beacon
filtering.
Emmanuel, maybe I'm missing something obvious, but isn't wpasupplicant
