There are a few sections in the driver which are not compatible with PREEMPT_RT. They trigger warnings and can lead to deadlocks at runtime. Disable the i915 driver on a PREEMPT_RT enabled kernel. This way PREEMPT_RT itself can be enabled without needing to address the i915 issues first. The RT related patches are still in RT queue and will be handled later.
