I have been living with this issue on my EeePC 701SD for some time and it has been very frustrating. I can confirm that the same issue Robie describes occur for my 701SD with r8187se wireless card (Fn+F2 causes a kernel panic when turning the wireless card off -- this doesn't seem to occur when turning it on if the netbook starts up with the wireless adapter off). This has occured in Ubuntu versions 9.04 through to 10.10. I recently switched to Debian Squeeze (testing, beta1), currently running 2.6.32-5-686 kernel and am experiencing an identical problem. I'm not experienced in debugging this type of issue myself, but would be happy to test any suggested fixes for the issue and report back results (though you would need to advise as to how to do this and what to include in replies).
