It's good to see that this problem is being examined closely. 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).
Testing would require that you have kernel source, apply the patches, and build
a new kernel with those included. On some distros, these steps are easier than
for others. Is your skill set up to this?
I will push the patch that changes the panic/crash into a simple warning with
the request that this be applied to stable. If/when this happens, you will have
that fix in your standard kernel. How long it takes will depend on the distro.
It is strange that I was not aware of this problem until Robie recently posted
in this list. Running the RTL8187SE on my computer has been a pain as the BIOS
in my computer does not have that device in its whitelist of approved devices.
As such, rebooting with it required that I shut down, remove the card, boot to
GRUB, and then hot-plug the card while being careful not to short it. That
changed in the past 2 days as I now have an ExpressCard to mini PCIe extender
that allows me to boot with the card installed. Unfortunately, I do not yet know
how to change the RFKILL setting with this device.

If building a kernel is as simple as building other programs from source
(i.e. configure, make, make install), I could do that. I'm using Debian
at the moment. Presumably I'd need a compiler of some kind, which I
could obtain from the repos. I am not sure how one would apply patches
to the kernel, however. Would I be able to compile a modified kernel and
add this to grub whilst retaining the ability to boot in the unmodified
kernel?
