Fedora Constantine, SYSRQ and needless swapping
By default, fedora disables the SYSRQ functionality of the kernel, for some reason. To enable it, either add sysrq_always_enabled at the end of your kernel line in /boot/grub/menu.conf, or edit /etc/sysctl.conf, changing kernel.sysrq = 0 to kernel.sysrq = 1 Some kernel updates on fedora also have the tendency to write to swap needlessly, even though…
