Not sure this is related, but when I enable DRM_I915_KMS=y I'm got stuck after boot too. When KMS is disabled I can at least get to the console (no graphics) This is with kernel 2.6.39-rc1. It worked fine with 2.6.38. I don't have much time bisect and reboot. Shell I try to pull drm-fixes for rc2 or use try this patch?
