Description

I have a repeating syslog message that spams my log with 10 lines per second of messages about "discard WME information element too short, len 7", although it's stuffed full of KERN messages and timestamps etc... so it's even worse.

Although this is gcc4hybrid hrev38293, this has been happening for several months now at least.

I'd really like to get this fixed somehow so that my syslog isn't rapidly growing all the time and really inconvenient to browse through and post for bugs etc.

The only other example of this message I find on Google is from a few comments from 7 months ago on a thread on the FreeBSD forum: http://forums.freebsd.org/showthread.php?t=8041&page=9

Where it appears to be better formatted and possibly more informative, and appears at the same rate. It seems to be a debug only message? In the FreeBSD logs, each message line is preceded by a message line about a beacon:

Jan 25 15:57:00 kernel: wlan0: received beacon from 00:21:91:02:e9:13 rssi 72
Jan 25 15:57:00 kernel: wlan0: [00:21:91:02:e9:13] discard WME information element, too short, len 7

Here's an example from the Haiku syslog with timestamps off:

Our wireless code has a lot of debug level printing atm. It still needs work if anyone is interested.
