I have been observing this for drives where the SCSI chain had term power problems. ISTR that it's been that more than one device was driving term power to the bus, and they apparently had some slightly conflicting idea about the actual term power level or such. So to be sure, it's IMHO always the sanest way to just have the host adapter driving term power, and have all drives leaving the term power line alone. This is unfortunately not the shipping state for most disk drives (i. e., they _do_ feed term power by default). -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
