If you're up to rev, give it a try. I'm going to send a much longer reply to Paul by e-mail, but the essence is that that problems were much more severe than this. I would like to repeat, however, that [1] i have not tested it under 4.30 (i believe i tested 4.21) [2] it only showed up on Newbury drives. (but that is what we had and it took months to get the system running). Note that the older Newbury drives have a known select problem. This was made worse by the earlier DG scsi driver, but even with newer Newburry disks we never got any to work well (panics in 1-15 minutes). - mike -- newton@csvax.cs.caltech.edu Beach Bums Anonymous, Pasadena President Caltech 256-80 (Hilo -- it's not just another rainy day!)
