slow kernel when memory = 8G 7446
Michael Heiming Do you mean this stuff? Handle 0x0017 DMI type 17, 27 bytes. Memory Device Array Handle: 0x0016 Error Information Handle: No Error Total Width: 72 bits...

Something else is wrong. I have a system with two Xeon (hyperthreaded) processors, an Intel E7501 chip set, and 8 GBytes RAM. It works fine and takes only a minute or so to boot up. The Xeons are 32-bit processors, but can address up to 64 GBytes of RAM by clever design that needs OS support.
I am currently running Red Hat Enterprise Linux 3 update 8. This has kernel 2.4.21-47.0.1.ELhugemem. The .config file for this contains, in part,
actually, "marketing" has never been a strong suit for them either. It's their "LEGAL" manipulations of vendors and compebreastors that has made them king...

This is a 32-bit kernel because my machine is 32-bit. A 64-bit kernel would not run on a machine with a 32-bit processor. The EIDE controllers and the SCSI controllers are all 32-bit as well. It is the processors and the chip set that do the mapping so that core-to-core copies are not required in the kernel. If your motherboard will accept 8 GBytes RAM, the processor(s) and chip set should allow you to access it all.
I did not have to do anything to the boot command line.
