Now, I use Debian 6.0.6 instead of Fedora 16/17. But I still sustain the problem of my wireless problem. If I enable/disable my laptop wireless device or my usb wifi adaptor, my laptop will panic. It seems like all the processes stop at that time and I have to restart my laptop directly.

P.S. I think I installed the drivers correctly and the linux kernel may have some bugs.

For example, when I unplug my usb wifi adaptor or I use this command,

ifdown wlan0

I encounter this problem.

Wireless Device:

PCI: 03:00.0 Network controller: Broadcom Corporation BCM43225 802.11b/g/n (rev 01)
USB: Bus 002 Device 005: ID 0bda:8176 Realtek Semiconductor Corp. RTL8188CUS 802.11n WLAN

My kernel is crashed when I shutdown my wireless device. – Yinyanghu Oct 8 '12 at 8:33

Is this Ubuntu? You seem to be using Debian. Please clarify.

Broadcom support for Linux is lousy, but there has been plenty of work done. See this question and the answers to see if it will help.

I think it shouldn't be the driver's problem, since I have two different wireless devices, both of them have the same problem! – Yinyanghu Oct 8 '12 at 4:56
It could still be a broadcom issue. I'd say blacklist any and all broadcom modules (b43, bcmwl etc) and try just using the Realtek device for a while. – fabricator4 Oct 8 '12 at 5:06
It doesn't work for me! – Yinyanghu Oct 8 '12 at 8:34
