POSSIBLE SMP KERNEL BUG ?

    I'm in the process of trying to setup a rackmount server to host my new
linux website on. I'm having (pardon my language) a sh*tload of problems.
Namely, anytime I try and use a SMP enabled kernel I get a kernel panic. I
can't figure out the problem. I've tried 2.2.14, 2.3.99-pre3,
2.2.12-20smp(rpm), getting the same error with different numbers. I don't
know if this is a hardware problem or a software problem(Kernel bug maybe?).
Nobody has been able to help me at all, and I've been re-compiling,
re-installing, and re-configuring for roughly 20 hours over about 3 or 4
days. Nothing seems to work. I _had_ it working with 2.2.14 for about 5
minutes (I saw both cpu's in /proc/cpuinfo), but when I rebooted again I got
the same kernel panic error.

     95% of the hardware on this system is brand
new with the exception of the video card which is an old one I had in a
drawer and I used it because I don't want to ship off one of my good vid
cards with the server. (I doubt it would be causing the problem.

    I've been using Linux for almost 2 years but I am still learning,
 and this is my first attempt at a SMP system. Maybe you guys(and gals)
can help, or send me in the right direction.

Thank you for taking the time to read this e-mail, hopefully you might have
a better grasp at the problem than I do.

Sincerely,

        J. Buset

The System:

Abit BP6 Motherboard (new, w/ factory bios)
        -all power managment in bios turned off, as was mentioned in the
          SMP-HOWTO
2 Celeron 500mhz ppga CPUs (new)
Maxtor DiamondMax Plus 40 - 30gb hard disk (new)
Trident 1mb video card
128MB of PC100 Ram (new)
3COM 3c905b NIC (new)
Rackmount 2U ATX chassis

Here is a copy of the error I recieved with a Stock RedHat 6.1 "Server
Install" booting with 2.2.12-20smp RPM kernel right after install. I hope I
didn't make any copying errors, I had to type it on a different computer:
