Using Ubuntu 11.04, I had the very same problem with my Thinkpad X120e.
Everytime I turned on the Thinkpad's WiFi adapter (a Realtek RTL8188CE in my
case) the system randomly froze.
Installing a newer kernel version (3.0.0-rc7) fixed this issue. Haven't
skimmed the kernel changelogs yet, so I can't confirm any changes
associated to the Realtek driver, but as a matter of fact, I haven't had
a single freeze up since updating to 3.0.0-rc7.
Nevertheless there is one drawback. It looks like the current fglrx package
won't build with 3.0 kernels.
In my case that didn't matter, as I prefer functional WiFi over accelerated
graphics any time.
You don't have to compile the kernel sources , Ubuntu provides 3.0.0-rc7 kernel
images with Ubuntu patches here:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.0-rc7-oneiric/
They can be simply installed by employing dpkg with the -i flag.
