Kernel 2.2.x did not support more than 2GB of memory because the hardware scatter/gather code used to support more than 2GB was never ported to it. For that, you have to go to the 2.4 kernels. > How can I force 2.2 kernels to see all the memory the server has? You can't. > Should I be using 2.4 kernels only? Yes. > If so, why do my compilations work but the 2.4 kernels do not work? They > end up in a "Kernel panic" message... This (failure to build a working SMP kernel) is a long-known problem with GCC 2.95.x; you must migrate to a later (3.x) version of GCC.
