Will attempt to capture some more logs when the card is working and when
goes into the problematic state.

Issue is in 4.7.0 too.
Wifi *may* stay working for fairly long periods (2-3 hours) in some
lucky instances.
Tests performed:
1. unload/load brcmfmac module.
Result : Interface is stuck in "Link is not ready"
2. suspend system and resume.
Result : Interface is stuck in "Link is not ready"
After a few days of testing the results are:
- During low network utlization i have seen the "no traffic" issue 2 times
during 5 days. Issue can be "fixed" by unload/wait 2 seconds/load of the wl
module.
- Suspend/resume - With unloading/loading the module on every resume i have not
seen any iss
Adding a cleaner version of the patch.
issues remaining:
- Current testing is ongoing on the "no traffic" issue, but it seems fairly
stable.
- The "wl" module should be unloaded before suspend and loaded on resume. Makes
it less prone to experience the "no traffic" bug. Do not know how or by who
Hi.
Ok? So you are using ubuntu 15.04? Remember that systemd does not run the
/etc/pm/sleep.d scripts, i use the pm-suspend command to suspend, that does

Hi Andreas,
Thanks for the assistance... What kernel-version and model of the wifi-
card are you using? Does it behave the same on both 2.4 and 5 Ghz?
For suspend/resume the pm-script seems to make it more stable atleast...
When/if getting the "no traffic bug" it's enough to unload/load the
modul
ngs to
finish before system is suspended. Got a few hiccups without it.

Update: There seems to still be a suspend/resume issue.
After each resume there is a chance that the wifi-card may stop working.
Have not dug into this yet, but at least the system as a whole seems
stable.
Behavior is that reception seems to stop working. It can transmit (and i
