I have a 2.1.5R system that has run under various configurations, most recently including a P6-200 board with the natoma chipset. I have used various SCSI interfaces, including an AHA-1542CP, and the on-board AIC-7880 of an older P5 board I used. But when I recently upgraded to the AHA-2940UW, I began seeing total system lockups every few days. The lockups do not seem to correspond to heavy disk activity, although there does need to be SOME sort of disk activity for it to occur. Once it was when I ran telnet. The disk goes to access, then all the system's SCSI indicators go solid, and the machine won't respond to anything except a physical power cycle. I have managed to always be at the console when it happened, so I have been able to reboot the machine (it doesn't reboot itself), but I am concerned that it may do this overnight or something. Hardware is as follows: Generic Natoma P6 board with one P6/200 96MB 60ns parity RAM: 2 32's, 2 16's. PCI cards: Adaptec 2940UW Digital Fast Etherworks ISA cards: Diamond Stealth VRAM Gravis Ultrasound (non PnP) SCSI disks: Seagate ST-43400N IBM DSAS-3540 (powered and on SCSI chain, but not mounted or used) Thanks for any ideas or recommendations Nick Grayphics http://www.grayphics.com
