System failure after a long term sleep
A lot of people have this issue (including myself). A simple Google search on Wake transition timed out after 180 seconds while calling power state change callbacks. Suspected bundle: com.apple.iokit.IOThunderboltFamily. will, at the time of writing this, give you approximately 145 pages dealing with this issue, and no one has any idea what is going on. This error seems to be stemming from some software issue without indications as to what causes it. It is annoying, and even though this problem has existed for quite some years now, nothing has happened.
