Thanks. Your logs make sense. You have config set to performance mode
by default (Which I believe default in all kernel Ubuntu). So as
expected Intel P state was asking for max. So there is no issue here.

But the behavior is different from what it used to be, isn't it?

So there seems to be a problem here AFAICS.
