It doesn't matter. If a platform is supposed to run Linux 3.6 then it 
has to run Linux 3.6 regardless of whether or not the failure is due to 
a firmware bug or a bug in the kernel. The platform vendor will be 
obliged to fix it in the firmware no matter what the test suite says.

Which is easily rectified if the specification is modified to describe 
reality instead.
