Your adapter is attempting to power down idle drives.  If you want to get =
rid of them (I've seen FreeBSD get very unhappy when you get too many =
transitions like this), go into the LSI WebBIOS (Ctl-H at boot), go to the =
adapter properties screen, and disable drive powersave mode.  The exact =
name of the property seems to vary from firmware to firmware.
