https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D264775 --- Comment #10 from crahman@gmail.com --- I didn't have time to address this last year, but the problem described in = the comments of this bug is related to a failure of the save/restore mechanism = of the cpu frequency. I've described in in more detail in differential D35704= .=20 In short, the cpu frequency is saved and restored as thermal control is activated and deactivated. But the restore mechanism breaks and so one end= s up with a low cpu frequency until a reboot. It would be very useful to finally fix this bug. Instead of maintaining this patch in multiple places, the latest revision i= s at https://reviews.freebsd.org/D35704 along with code to allow active/passive cooling to be controlled by power_profile. --=20 You are receiving this mail because: You are the assignee for the bug.=
