After updating to kernel 3.1.6 I get these two errors every few seconds:

Jan 22 17:16:48 dctn007 kernel: ERROR @wl_cfg80211_get_station : Could not get rate (-1)
Jan 22 17:16:48 dctn007 kernel: ERROR @wl_cfg80211_get_station : Could not get rssi (-1)

version is broadcom-sta-

Reproducible: Always

Steps to Reproduce:
1. modprobe wl
2. /etc/init.d/net.ethX start
Actual Results:  
Many errors in syslog

Expected Results:  
No errors :-)

Fix to remove the error output from driver source

This is NOT an actual fix to the source of the problem. It just removes the error output in the driver. If someone could figure out as of which kernel version this problem occurs, the patch could be applied conditionally. In 2.6.36 the problem did not happen, in 3.1.6 it does.
Comment 2 Federico Pires 2012-07-24 20:31:17 UTC

I noticed the same thing with hardened and gentoo sources 3.4.2 and 3.5.0, and I think it *might* have something to do with the fact that iwconfig does not always report the "Quality link" and "Bit rate" information.

I used a patch (attached) to remove the flood in syslog from this debian bug report:

I removed the first part, which is already present for the current ebuild in the other patches. 

I'm currently using the module, and the flood in the log is gone, and no issues so far with my wi fi. For what I understand, as Ole said, this does not look as an actual fix, but rather getting rid of the logging flood.

*** Bug 430134 has been marked as a duplicate of this bug. ***
Comment 5 Peter Leugner 2012-09-27 19:40:48 UTC
Could the ebuild please call epatch_user, so we could use attached patches without hassle? That would be great....
Comment 6 M. B. 2013-04-26 04:45:01 UTC
This seems to be fixed by version - see the latest ebuild in bug #438622

i'm afraid in version 5 of the driver this will be a WONTFIX.
Comment 7 M. B. 2013-05-03 00:04:36 UTC
Included the patch. It should hit upstream as soon as a dev commits it. Please refer to #438622 for further details.

Until then, get them from my overlay; tbc in layman.
