Just as a side note, this patch is not in the Linus tree yet and thus not in Greg K-H's stable queue.

Anyway, I hope this fixes my wireless troubles as well.

Quote from my conversations with the iwl folks at Intel:

----- Begin Quote -----
We have something that is somewhat similar. Are you in a very silent environment?
In this case, https://git.kernel.org/cgit/linux/kernel/git/iwlwifi/iwlwifi-fixes.git/commit/?id=12f853a89e29f50b17698e17e73c328a35f1498d might help.
It is queued up for 3.15 and I CCed stable for 3.14.
----- End Quote -----

As such, it should get there soonish.

I see this made it into linux 3.14-5. Will play and see what I can make happen (or hopefully, not make happen!)

As an observation - I haven't seen this issue reappear. Thomas? Do you see the same?
Comment by Thomas Bächler (brain0) - Thursday, 17 April 2014, 05:54 GMT
I have not seen the "timed out" thing, no, but I am still not happy with the stability of my wireless. Anyway, this is a different problem. Closing.
