If you need anything else, please let me know. Oh and apologies for all the additional comments. I've since replaced my card with an Intel based card so if it helps I'm more than happy to donate the BCM4313 based card to anyone who wants to work on it. I have been digging into this issue last week and reworked the code in mac80211 .flush() code path (which is in comment #2 trace). I will mention this bug report in the commit message. This still happen on latest kernel. This is the exact backtrace I got.

A patch referencing this bug report has been merged in Linux v3.8-rc7: commit 7b2385b95363c9ff49801c19cba2489a05bd6672 Author: Arend van Spriel <arend@broadcom.com> Date: Sat Feb 2 14:36:50 2013 +0100 brcmsmac: rework of mac80211 .flush() callback operation Linux 3.8.2 - connection still hangs at some time, now without anything in dmesg. I also still get hangs under 3.8.3, though it looks like it is a lot less frequent than before. I did have these messages in dmesg, which may or may not be related.

I also get these "Pkt tx suppressed" messages, but I get them much earlier than the hang happens. I spoke to soon when I said it was a lot less frequent. That was based off transferring a large file from a computer on my local network, where it only stalled once. In a more real-world test of updating, it was as bad as before, or maybe even worse. On top of that, a couple times it deauthenticated from my network and would be unable to authenticate again until I restarted. (though I'm sure I could have reloaded the proper modules instead) That update included kernel 3.8.4, and after that update I can't authenticate at all. I am using opensuse with Linux 3.7.10-1.1-desktop on lenovo y570 with BCM4313 (rev 1) and the connection brcmsmac is very bad. There are random disconnects, a lot of packet loss and overall connection is pretty bad. I have similar hardware on my lenovo e135. Wifi have never worked good (3.14.* and 3.15.1). Signal was very weak and device was almost useless. I used wl driver, but it produces ops time to time and binary driver has known disadvantages. I build the kernel 3.16.0. It looks like it works good! It need confirmation, because my access point is very close to notebook.
