CONFIG_X86_IOPL_IOPERM was disabled. This is enabled by default in Debian, I was running a custom kernel on Debian and didn't check the GRUB boot order. If this switch ever gets disabled or disappears in the kernel though, LinuxCNC will not function. IOPERM and IOPL is considered legacy, but Debian keeps the dinosaurs around so this shouldn't be a problem any time soon except maybe on sid/unstable.
I really appreciate the help everyone but this issue has been solved awhile ago. I don't want to cause further confusion on this problem so please disregard this thread unless you build your own kernels. When I make the LinuxCNC ebuild, I'll have it run several checks to make sure the PREEMPT_RT kernel config is properly set on Gentoo systems.
