It should still do wake-on-lan, although the fxp driver doesn't support that right now - it doesn't appear to be a useful feature. Powersave transitions (D0 -> D3) should also still work. What the fix does is prevent the board from reducing power in idle state, which is a subset of D0. (Intel has D0-active and D0-idle, or some such). -- Jonathan To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
