That is exactly the problem with this sort of issues..

That's strange. 3.13 is way before any changes that could have had any
such effect. Can you by any chance try with older kernels to see where
it starts misbehaving for you? 3.12? 3.10? 3.8?
Can you try keeping an eye on the osdc sysfs file when this happens the
way I suggested in another post?
Thanks,
