https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D217247 --- Comment #8 from Konstantin Belousov <kib@FreeBSD.org> --- (In reply to St=C3=A9phane Lesimple from comment #7) I also asked for sysctl output. >From what I see in the dmesg, your CPU's LAPIC does not work in C2/C3. The fact that TSC is also not invariant forced the kernel to disable C2/C3 entrance, which you noted as well. There is also r309189 which downgrades LAPIC eventtimer quality. I am not = sure that the commit is important for your machine, since it refuses to enter C2= at all. Yes, I probably also want to see verbose dmesg and sysctl output for 11.0. = I might provide a recipe to restore C2/C3 usage after I see the data. --=20 You are receiving this mail because: You are the assignee for the bug.=
