Custum kernel, post or link to your KERNEL_CONFIG, or better yet a dmesg. Also I'd suggest testing this first w/o SMP enabled (not sure if SMP is even that helpfull with hyper-threading IMO) and secondly test with AICP disabled as well. I may even go as far as running the system w/o SMP and hyper threading enabled for testing purposes. Doing this will help limit the variables at play here, and is generally considered good debugging practice. Finally, I would post any debugging or error messages your are getting in your logs as well. -pete -- ~~o0OO0o~~ Pete Wright www.nycbug.org NYC's *BSD User Group
