Well, I remembered that I have disabled the WLAN (BCM4312) via BIOS so that I can use my computer. So, to get you a version that shows the bug, I re-enabled WLAN and rebooted. The system hard-locked as expected. I powered off manually and, after disbabling the WLAN controller, I am attaching Xorg.1.log which shows where the lock occurs. I hope this helps.
