[ltp] ACPI suspend problem on T23

Khosrow Hassani said about ACPI suspend problem on T23:

Khosrow:

You may need to add more to your action file.  I suggest adding the following:

/sbin/hotplug stop 
before invoking the sleep/hibernate command and

/sbin/hotplug start
after the command.

Hotplug should find and reinable your devices.  I'm assuming that you are using a USB mouse in this case.
