<pre>Hello,
I noticed that the "enable_rc6" parameter is gone since kernel 4.16 and found
out the reason is that there aren't any bugs related to it anymore.
Unfortunately this is not true. Lenovo's V310 and V510 laptops massively suffer
from random freezing and so far the only fully working solution has been to set
the mentioned parameter to 0. The "enable_dc=0" parameter alone is not enough
as the freezing is back since kernel 4.16.
Is there any way of a passing an equivalent parameter or any way to turn off
RC6? If not, on behalf of all owners of laptops mentioned above I kindly beg
the developers to consider the non-negligible effect this deprecation will have
on us.
More on these Lenovo laptops freezing:
