Possible Fix for Wireless Freezes

It has been a known issue for sometime that some wireless cards will freeze or panic the system on PC-BSD/FreeBSD 8.x. Some cards do this intermittently while others do it quite regularly. The problem seems to have been narrowed down to a conflict between devd and the netif startup script as it only occurs when devd is running.

Earlier this week Kris committed a fix which will show up in the next snapshots for 8.2 RC.3 and 9.0. If your wireless card is affected and you’d like to test the fix now, try adding this line to your wpa_supplicant.conf file:


Let us know if it makes a difference on your system!

    I have PC-BSD running sweet so far on a MacBook Pro (mid 2009) 15″. I have only been up a few minutes. But wanted to let Kris know how I did it. I have yet to figure out where to post this. Email me or something please. Thanks.

    Yes, indeed.
    I need to fill up that string to avoid freezes when trying to configure the network from the GUI.

    Also, I needed to set immutable flag on tthe file, otherwise at some point it got overridden.

    chflags schg /etc/wpa_supplicant.conf
