    Kernel Panic lockup with Broadcom 4318

    Hello fellow Fedora users:
    I have installed F12 on an Dell C610 Laptop. So far I really like the GUI, performance, and it not being Windows. As a new to Linux forum member I am trying to be worthy of all your dedication to this calling. I originally has a Linksys USB wif adapter, downloaded the firmware, got it to load and run but could never get connected.

    So I bought a PCI card that fits in the laptop. It is Broadcom 4318 based (Airforce 54g). To my great surprise, after installing and booting, the wifi was up and running, connected to the access point. However, when I actually started to use the link (loaded Mozilla) the system hung big time.
    The screen froze and the caps lock and scroll lock LEDs flashed in unison. I found out this means a "kernel panic". This happens every time within 2-3 minutes of loaded a browser and putting traffic across the link.
    I rebooted and connected across the link but did not load any internet application and the laptop ran for over an hour just fine, just like it has for 2 weeks since I did the install. But as soon as I loaded Mozilla and did a google search, bam, locked up.
    Below is the output of the WirelessSetup script. I would love to begin using Fedora and beginning to program on this platform. Since this appears to be a kernel problem, I hope fixing this is of some benefit to all.

    Output of WirelessSetup:

    The bcm4318 is one of a very few broadcom cards that works with fairly new open firmware. And to date Fedora is the only distro which includes this open firmware out of the box.

    I have a laptop with the same card and Fedora installed - though I use it very infrequently, I haven't seen the same problem.

    One thing I note in your output is this
    Bit Rate=1 Mb/s
    That's very slow. My card shows a more normal bit rate of 54 Mb/s. I don't think this is related to the crashes, but you might be able to fix that with
    su -
    iwconfig wlan1 rate 54M
    Does the lockup happen with any browser or only firefox? Does it happen when you connect to say, download a package or upgrade using yum?
