What is the nature of the fn-f4 key on your laptop? do you have it
set to generate an acpi event that you have linked to a script? Also
how do you have it set to control both the video and wifi? Did you
also update your kernel? Sounds to me like an acpi issue. Finally
what radeon chip are you using?
