The i915_setmode function did not crash. The printk output from that function seems the same as the one that is in 3.6 kernel. I also include the 3.6 and 3.7 kernel dmesg. The black screen is 100% reproducible. Any suggestion how to further debug this i9515 black screen problem? I really want to get it fixed.
