Yes the issue is the firmware's response to the keystroke. The
intention here is to individual submit machines in future patches as
they're discovered. The parameter's primary purpose is to assist in
building the list. If someone reports a bug with these symptoms, they
can add the parameter to their kernel command line, and report if it
helps them. If it helps, their machine can be added to the DMI table.
