Thank you for the reply, Andi. This kernel is compiled with the .config from the original FC5 release, which used kernel 2.6.15. I just ran "make oldconfig" on it and accepted the defaults. So it is, I believe, a 4GB/4GB split. Does that make a difference? Thanks, Steve Bergman -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
