Sorry to be so late, but I thought I had an interesting data point.... A month or so back I was working on a ncr driver issue crashing a 3.4-stable system. I had a simple torutre test which a) ran a dozen or so cpu-bound programs, b) ran a dozen random IO disk benchmarks, and c) got ping flooded by a couple of other hosts. The results were: with ncr0 driver, system would crash in an hour or two with sym0 driver, system chugged away for days. with ahc driver on a 2940U2w the fxp would timeout every 30 seconds or so. This was a 3.4 stable system on a 2x500 P-III Intell NLX440 MB in a 2U case. SMP was enabled, no IRQ's were shared. I never had a chance to investigate it further:( --- David Miller To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
