pm-suspend could reproduce this bug, fail rate is around one out of ten.

steps to reproduce this message instead of using checkbox:
  * boot the system
  * use command "pm-suspend", then the system will go to suspend
  * after make sure the system has suspended, click mouse or keyboard to wake up the system
  * command "dmesg | grep PSR" to check whether the message pop up
  * if no such message, use command "dmesg -C" to clean the buffer and do the steps again from the bullet 2 until you get the message

This seems that the buggy firmware, set the method _PSR as NotSerialized, but create the objects.
As from the ACPI spec mention,
Functions are equivalent to a Method that specifies NotSerialized. As such, a function should not
create any named objects, since a second thread that might re-enter the function will cause a fatal
error if an attempt is made to create the same named object twice.

        Device (ACAD)
        {
             ...
            Method (_PSR, 0, NotSerialized) // _PSR: Power Source
            {
                CreateWordField (XX00, Zero, SSZE)
                CreateByteField (XX00, 0x02, ACST)
                Store (0x03, SSZE)
                If (ECON)
            ...

suggest the firmware should modify the ACPI table for the _PSR method as,
            Method (_PSR, 0, Serialized) // _PSR: Power Source
