I'm running two p60 32mb eisa with AHA27xx. I have some HP drives and some seagate barracudas. Going to ditch the HP soon. I beat up on them pretty heavily and do not see a problem. My motherboards are those weirdo broken DMA boards so even though I have 32mb I have to use bounce buffers. Just for grins you might try a kernel with bounce buffers and see if you get the hangs. Another dumb idea is that something else is causing the problem and the symptom is a scsi timeout. I've made this mistake and chased a wild goose. I don't wanna open the box and find out what my adaptec firmware rev level is but...... The only other i/o in the boxes are the EISA style 3c509. I am running the -current build from June 30'th.
