Enabling RC6 may cause system hang on Lenovo S510 after idle for
a while. It also makes Asus ET2012E sometimes fail to resume from
suspend.

Although upstream developers would like to figure out the root cause,
but it may take time. We may disable RC6 on these models before
the root cause is found.
