You'll need to update more than just the kernel.  There were issues with
Test 3 for udev and network init scripts that didn't distinguish between
the wmasterX and wlanX interfaces, and since both have the same MAC
address things got confused.

Try updating to the latest Rawhide bits rather than using Test 3.  The
make sure you remove the following files:

rm -f /etc/sysconfig/network-scripts/ifcfg-wlan0*
rm -f /etc/udev/rules.d/70-persistent-net.rules

The initscripts don't care what's after the ifcfg- (because you could
name it ifcfg-Home or ifcfg-Some-Other-Place, it doesn't have to be the
device name) and therefore even a ifcfg-wlan0.bak will cause the problem
too.
