I did not touch a lot of hardware, but I have a lot of problems with Dual P3.
I am using a single CPU machine as comparison:
Single 1: Laptop T40, 1.5 P4 Mobil, 512M PC2100. Everything is running perfectly.
Single 2: P2-350 FSB 100, 160M. Everything is very slow but very stable.
Dual 1: Compaq AP400 Dual P3-600, 256M Reg ECC PC100. Everything is ok, except it will freeze on RealPlayer etc real time media application, so must be physically power off. This machine has a hot old 4G SCSI
Dual 2: ASUS CUR-DLS, Dual Coppermin 933 Socket 370, 1G Reg ECC PC133. That is the worst machine I ever had. It does not freeze on Realmedica, but will automatic reboot if the file is little corrupted (IBM T40 will simple go past the point). It will crash IE. Reboot on IE. Reboot on Flash. Automatic reboot on anything. CPU is 51C and 56C at full Speed. It will even reboot/crush when it is cold. I ran SiSoftware Sandra, and other testing software to burn the hardware: HD, RAM, CPU: all passed. no problem. only in real world applications: IE, Flash, RealPlayer. (Under W2K)
Is Dual really that unstable? Is Dual only ok in Text Mode, like Linux/FreeBSD? If the problem is only related to my hardware. What could be wrong? Bios is updated. Everything is passed burn test.
It is something hardware related. Dual core systems are not unstable when setup correctly. For that matter most of dual core systems use a server quality systemboard which are built for servers with reliability in mind.

I do management on a number of multiprocessor machines with no outstanding issues.
Perhaps your kernel does not have driver support for your devices? Or perhaps the support built in, or the modules are outdated and limited in their functionality? There are a number of things that could be attributed to the problems you are having - upgrading software and drivers would be the first step to resolving this.
I strongly think it is a problem of Dual in general. Not only my duals all have the same problem but I guess a reason why.
When playing real player movies .RM or .RMVB, the frames show that at least W2K does not support Dual well. If I use a single P3-500, with everything the same, I got a bad quality but ok playing. But when I use Dual 600, instead getting

Not true. We run many Dual XEON win2000 and win2003 boxes with zero issues. However all of this is on newer hardware.
It could be very well an issue with RealMedia's support for Dual Processors. If Realmedia is designed to use all available processors, it could very well be having issues managing multiple threads across the different CPUs. Try playing a file in Windows Media player and see if you get the same issue. If you do, its probably hardware
step 1) upgrade your bios
step 2) upgrade your bios
step 3) upgrade your bios
I can't agree more ....
