Hi, I am also having the same problem, first removed the ~/.Xauthority file it worked fine for the next two-three shutdowns, then it started again. Then I added acpi=noirq switch in the kernel parameter and seemed to be fixed for couple of weeks, then it started again. Moreover, after acpi=noirq, the bluetooth has stopped working.
