I know such things very well but I have to say that it only happens in case of hardware or driver failures. I never got problems because of softupdates itself. The cases I got were a disk with broken TQC in the firmware and some data- coruption in some vinum versions using R5. Softupdates seem to be able to trigger bugs in other layers. -- B.Walter COSMO-Project http://www.cosmo-project.de ticso@cicely.de Usergroup info@cosmo-project.de To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
