I tried that on my A7M266D with no effect. I believe something in recent pmap code doesn't like this mobo, or maybe dual athlons in general. I can run RELENG_5_1 rock solid, and -current from 9/24/03 rock solid, but -current from 10/3 or later gets random sigs and eventually panics. I have scsi disks so it's not ata. -- Barney Wolff http://www.databus.com/bwresume.pdf I'm available by contract or FT, in the NYC metro area or via the 'Net.
