Re: Crashing when SMP enabled
I had a similar problem with my setup. I found that by disabling any parts of the mother board that I did not use helped alot. So for example I disabled the nvidia ethernet card(I use the marvel one) and Sil SATA controller(I use the nvida one). What I was finding is that the problem really comes down to a timing issue. It seems the system speeds up the clock under load. Try compiling something and look at your time(make sure you can see seconds). I put ntp on my system and all seems to be fine. O one more thing it was more of a problem on older kernels(like yours) im on the latest(220.127.116.11) and its fine.
AMD64 X2 4400, ASUS A8N-SLI Preimium, eVGA nvidia 7800 GT, OCZ Platinum EL-PC3200 2-3-2-5 2gig 200gig WD SATA150, SB Audigy 2 Platinum, Pioneer 108, Dell 2405W, all running on Gentoo Linux ~amd64.
