After updating to 3.8 kernel today, I am now getting a kernel panic when I run iwconfig. I am able to connect to wireless networks just fine, but when I run that to check my connection speed, I get a kernel panic. If I boot in to an older kernel, it works fine. Also, regardless of what kernel I am booted in to, the Network Settings for wireless connections just show disconnected even if I am actively using them.
EDIT: I am using Fedora 18 64 bit
