I don't think its chipset or memory, the machines that crash have different brand
motherboards with different chipsets, I ran docmem for 24 hours on each stick of ram
and found no errors. The ram worked fine in my WindowsXP machine, and it works fine
when I use the non-smp kernel, and/or when I take the ram down to 2 sticks (512
meg). I'm posting here because I believe I have narrowed it down to a bug in the
kernel.
