--- Comment #1 from Viktor Štujber <[email protected]> --- After failing to find the regression window and discovering that the previous kernel with the new userland also exhibits the problem, I again tried searching for existing discussions about the subject. I found https://lists.freebsd.org/pipermail/freebsd-stable/2015-March/082034.html from march 2015 which points to a 1 year old change in HEAD, https://svnweb.freebsd.org/base?view=revision&revision=265329 . Here the committer references some other mailing list discussion, which concluded that P-state power management is not effective and can interfere with C-state power management. That is nice and all, but this Intel Atom CPU does not have any C-state power management. Using P-states has a measurable impact (a few watts). Undoing the changes to /boot/device.hints is what I did for now. -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "[email protected]"
