I concur that this is not a duplicate, FWIW.
My read of this (288863) bug is that the failure mode is that the computer fails to shut down, the last thing displayed is "acpid exiting."
The "hang" in 274995 isn't a hang but a long delay (about 2.5 minutes). The hang in the reports involving "acpid exiting" seems endless.
