I've been experiencing something strange lately after applying optimization settings from: http://wiki.freebsd.org/TuningPowerConsumption I can't get a useful dump either, the machine is idle, and the backtrace is strange to me: db> show allpcpu Current CPU: 0 cpuid =3D 0 dynamic pcpu =3D 0x692d00 curthread =3D 0xffffff0001507390: pid 11 "idle: cpu0" curpcb =3D 0xffffff8000039d40 fpcurthread =3D none idlethread =3D 0xffffff0001507390: pid 11 "idle: cpu0" curpmap =3D 0 tssp =3D 0xffffffff80840580 commontssp =3D 0xffffffff80840580 rsp0 =3D 0xffffff8000039d40 gs32p =3D 0xffffffff8083f3b8 ldt =3D 0xffffffff8083f3f8 tss =3D 0xffffffff8083f3e8 cpuid =3D 1 dynamic pcpu =3D 0xffffff807f85ed00 curthread =3D 0xffffff0001507720: pid 11 "idle: cpu1" curpcb =3D 0xffffff8000034d40 fpcurthread =3D none idlethread =3D 0xffffff0001507720: pid 11 "idle: cpu1" curpmap =3D 0 tssp =3D 0xffffffff808405e8 commontssp =3D 0xffffffff808405e8 rsp0 =3D 0xffffff8000034d40 gs32p =3D 0xffffffff8083f420 ldt =3D 0xffffffff8083f460 tss =3D 0xffffffff8083f450 db> bt Tracing pid 11 tid 100004 td 0xffffff0001507390 rman_get_bushandle() at rman_get_bushandle+0x1 sched_idletd() at sched_idletd+0x123 fork_exit() at fork_exit+0x118 fork_trampoline() at fork_trampoline+0xe --- trap 0, rip =3D 0, rsp =3D 0xffffff8000039d30, rbp =3D 0 --- -Brandon
