Revert them, please. The above request was apparently not sent to the Author/Committer of "sys/power: Sleep type reporting by PM backends" ( e779891327b1 ) and related: Aymeric Wibo ( obiwac@FreeBSD.org ) --at least there is no reference to the name or Email address in the above quoted text. So this CC's the author of that and the other commits. My amd64 context is one of those getting the very late crash during "shutdown -r now" or "poweroff". (PS2 keyboard use required, not USB keyboard --but it is too late for dump to work as well.) =3D=3D=3D Mark Millard marklmi at yahoo.com
