 I made few extra steps and looks like this PR should be reassigned.
 After booting custom kernel I got:
 
 dodo$ addr2line -e /usr/obj/sys/arch/amd64/compile/TEST/netbsd.gdb 0xffffffff80545844              
 /usr/src.current/sys/external/bsd/drm2/dist/drm/i915/intel_pm.c:3628
 
 
 3623 /* Check that the pctx buffer wasn't move under us. */
 3624 static void valleyview_check_pctx(struct drm_i915_private *dev_priv)
 3625 {
 3626         unsigned long pctx_addr = I915_READ(VLV_PCBR) & ~4095;
 3627                                                                                                    
 3628         WARN_ON(pctx_addr != dev_priv->mm.stolen_base +
 3629                              dev_priv->vlv_pctx->stolen->start);
 3630 }
 
 
 Kernel built wihtout DRM support boots fine.
 
 Computer itself is a cheap laptop with Intel N2840[1] and something 
 described as "Intel Corporation ValleyView Gen7 (rev 0e)" GPU (it is
 a low-end Ivy Bridge variant).
