Reupdated patch (and yes this one compiles): From: Clark Williams <williams@xxxxxxxxxx> Date: Thu, 21 May 2015 12:51:53 -0500 Subject: [PATCH] [rt] i915: bogus warning from i915 when running on PREEMPT_RT The i915 driver has a 'WARN_ON(!in_interrupt())' in the display handler, which whines constanly on the RT kernel (since the interrupt is actually handled in a threaded handler and not actual interrupt context).
