Description of problem:
Unplugging an rt73usb dongle causes an immediate kernel panic, even if it hasn't been used to connect to any networks. I am currently using a Linksys WUSB54GC on a Thinkpad X31 (i386), but I have reproduced this on x86_64 as well.

Netconsole log attached.

Version-Release number of selected component (if applicable):
kernel-2.6.18-152.el5

I do not know if this is the same i have a e620 huwai modem when I unplug it while connected I get a crash and all I am shown is the plymouth fedora logo.

I originally had this problem when my modem was not detected by Network manager and had to use system-config-network to make a manual connection. After i reinstalled the problem disappeared.

Sorry did no see the product I use fedora 11
