The saga is about to conclude.
The Gigabyte motherboard GA-MA790FX-DS5 with an AMD Phenom quad-core is unstable under full load, period. I suspect the memory controller setup, but Gigabyte has been unable to reproduce (under Windows).
Last week I purchased an MSI board (K9A2 CF) with slightly lower specs (primarily AMD790X instead of -FX chipset) - yesterday I installed it with the same components (cpu, psu, memory, disks etc.). Earlier this afternoon it completed a 24 hour burn-in run with mprime stresstests going at full throttle - showing no problems whatsoever. Right now it's running four copies of mprime plus a Kubuntu installation in Virtualbox, and a Firefox3 beta. (I'm browsing the net whilst waiting for Kubuntu to make some progress).
IMO the Gigabyte board is faulty - I'll ask the dealer to take it back tomorrow.

Per, I'm beginning to suspect that it's not just the Gigabyte board that is having the problems with x86_64 and AMD multicore processors. I don't know if you have seen my post asking for your help yet, but I am in the exact same boat with a Tyan Tomcat K8E S2865ANRF Socket939 with Opteron 185 (Ver 2.00.00), (2 Gig OCX Platinum -- certified by OCX in Denmark and returned 2 weeks ago) and a pair of Seagate 500G drives in raid 1. It's not memory, there are no errors and the box will run just fine at idle but crash when you put it under load. (not very functional regardless of the specs) At least in your case with the Gigabyte board and in my case with the Tyan board, there is something in the 10.3 x86_64 setup that is crashing under load and leaving nary a trace as to why? The Tyan board even supports Linux. I don't know what is new in the dual core chipsets on the boards, but somewhere there _is_ something rotten in Zürich (or is that Denmark?) What is helpful and unique about the Tyan board is that is comes with an onboard (literally on the board - you have to take the side cover off) 2 digit lcd display that shows the current bios state and bios codes for the current state of the machine. I have watched and logged all bios codes and watched it run through its internal self tests and everything is shown as 100% OK. No problems from POST to fully loaded in KDE. I have also turned all unneeded peripherals off in the bios to eliminate any irq conflicts and booted with and without noapic and nolapic - makes no difference. I suspect it may be worth a bug report to investigate given that we now have a Gigabyte and Tyan boards experiencing the same thing. I searched bugzilla.novell.com and didn't find any other entries. Did you file a bug report? If not, I'll try and get one in next week. -- David C. Rankin, J.D., P.E.
