Git rev: master/835f7eac0610325e906591cd81890bebe8627580

Steps:
1. Download the wic image from the above site
2. dd the image to MircoSD card
3. Boot up the board
4. Run command "shutdown -h now"

After run command "shutdown -h now", all processes are stopped but at the end the board can not power off. The screen hangs on the splash image.
There is no such issue in previous build.

Here is the log:

Same issue happening on genericx86-64.

This issue only happens if the board connects a LCD display with mini HDMI cable.
There is no this issue if I disconnect the display.  

When the bug occurs,  it will report an error on screen:

Error VT_WAITACTIVE failed
: Interrupted system call

This has been fixed by the following commit:

    psplash: Avoid mount the psplash tmpfs twice
    
    The /etc/init.d/psplash.sh will be invoked both in boot and
    shutdown/reboot. And the psplash tmpfs will be mounted twice. This
    will trigger a bug in umount and let the system hang when
    shutdown/reboot. I already made a patch [1] to fix the issue in
    umount, but there is no reason for the psplash to do the twice mount.
    So also fix it.
