Well this _seems_ to have fixed it.... I've got my remote backups of three machines (isn't rsync/ssh great!) onto the MO drive, and i set news.daily running at the same time.... no lockups since. So i just changed PCI latency to 32 and disabled all those PCI burst options things :) Thanks for all the assistance guys.. I was really pulling my hair there for awhile (was about to douse in petrol and burn the thing :) Regards, Peter -- Peter Childs --- http://www.imforei.apana.org.au/~pjchilds Finger pjchilds@al.imforei.apana.org.au for public PGP key
