https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=295941 --- Comment #4 from Andrew Gallatin <gallatin@FreeBSD.org> --- (In reply to ShengYi Hung from comment #3) I'm not sure what you're asking me to try. Again, I think my system was *ACCIDENTALLY* stable with the state of intel_hwpstate before 7b26353a59d6. I don't think that commit was buggy I'm actually quite happy with my current workaround, which is to set the iccmax MSR to 100 (*8), and to keep epp around 20 or so. That prevents my box from power cycling, but gives slightly better performance in terms of buildkernel time and lets the fans get quiet when idle. Anything below 20 seems to draw another 2j or so of power (according to Intel pcm from ports), and prevents the fans from going silent. Eg, I think I'm actually in a better place since I stopped using epp to fix a problem it was never designed to fix. -- You are receiving this mail because: You are the assignee for the bug.home | help
