Well, first let me apologise. My hang was due to kern/uipc_socket2.c 1.63 (now fixed). Nothing to do with the scsi code. My resets may have disappeared too. I'm fairly sure now that I do actually have a dodgy cable (as you said) - twiddling it about a bit seems to have helped. In my defence, I hadn't upgraded this machine for over a month, decided to look at getting some digiboard stuff working, upgraded the system, and while rebooting, took the machine apart to take the digiboard out and have a look at it.... When things started going wrong, I saw lots of ahc updates and jumped to the wrong conclusion :-/ > Ken > -- > Kenneth Merry > ken@kdm.org Cheers. -- Brian Don't _EVER_ lose your sense of humour !
