This bug has been assigned to the wrong component.
Can you provide an output of theses command.
(or the smolt profile for your laptop)
This also seems useful, a "full" dmesg output. (once with RFKS on, and the other
off) and also dmesg |tail when switch goes from ON to OFF.
(Pick "Create a New Attachment" to upload each file )
Note that we usually say that RF kill switch (Radio Frequency Kill switch) is
OFF when you can use your wireless, whereas is it is ON when wireless is disabled.

dmesg output when switching rf killswitch on to off
Can you replicate this issue with the kernels here?
Booted the new kernel with the rf killswitch off, logged in then system hung
with caps lock led flashing.
Booted the new kernel with rf killswitch on, system working fine, no wireless,
switch rf kill switch off still no wireless but system did not hang.
