    Default Atheros module warnings filling syslog!

    I am booting Backtrack3 from USB and saving changes to a partition on my hard drive. This partition is also used when I boot into Ubuntu, and I noticed that I had run out of drive space!

    Further investigation revealed that the 'changes' folder on my Ubuntu partition had reached 1.5GB! I was able to determine that /changes/var/log/syslog was 1.3GB. It was filled with warnings from the wlan and ath_pci kernel modules. These are accumulating as soon as I put my Atheros card into monitor mode using 'airmon-ng start wifi0'.

    I have since changed my /etc/syslog file to capture critical events to syslog instead of warnings, but wanted to pass this info on to see if anyone else is experiencing this.

    It writes at about 550kb/sec to syslog!

    Setup:
    Backtrack3 booted from USB on Dell D610
    Airlink101 AWLC4130 (Atheros 54/108Mbps)

    I had the same problem you did, and did the same fix as well.
