There's a kernel config option called "High Memory Support" with three options: less than 1GB, between 1 and 4GB, and greater than 4GB. fix: a recompile would be required in this case. If you want to check your current kernel config to see if that's the problem, look at /boot/config-<your_kernel_version> and find a few lines starting with CONFIG_HIGHMEM. All should be commented out (line starts with #) except the one that's actually enabled. Besides... check if your bios supports that -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
