Recent versions of X are thought to be OK. It's the exact same issue described in this paper, scroll down to section 4.5. http://www.cs.utah.edu/~regehr/papers/hotos7/hotos7.html There's absolutely nothing the kernel or PREEMPT_RT can do about this, AFAICT even RTAI would be affected, because X lets userspace drivers talk directly to the hardware including wedging the PCI bus.
