[1.] One line summary of the problem: Computer hangs/freezes before shutting with the text "* Will now halt" on the screen, starting from patch a3c08e5d80c54e32423efbba113b02942c91f726. [2.] Full description of the problem/report: When I issue the command "shutdown -P now" and wait for the computer to shut down, it goes through all the steps - seemingly - but hangs with the text "* Will now halt" displayed on the screen. There is no response to keyboard events: ctrl+alt+delete, caps lock and num lock keys have no effect. This is a regression that was introduced with the following patch (found using git-bisect): commit a3c08e5d80c54e32423efbba113b02942c91f726 Author: Thomas Gleixner <tglx@linutronix.de> Date: Fri Oct 8 20:24:58 2010 +0200 x86: Convert irq_chip access to new functions Before moving the irq chips to the new functions, fixup direct callers. The cpu offline irq fixup code needs to become generic and archs need to honour the "force" flag as an indicator, but that's for later.
