You might want to take a look at the Linux kernel amilling list. One of my
friends had issues with his dual Xeon and 4Gigs of RAM. In his case, Windows
would claim to see the 4Gigs but would actually crassh when he actually came
to use more than 3...sounds fammiliar?
In Linux, he'd get a kernel panic on boot (2.6.x kernels)...after over 6
months of poking at forums and the LKML, his bug was officially received as
valid from the kernel gurus and eventually fixed....
hope this helps a little in your investigation...
