Hi
   Will you please try the latest kernel(2.6.30-rc7) and see whether the issue
still exists?
   IMO this issue is related with the broken BIOS. OS will verfity the power
state again in course of power device transition. If it is not the expected
power state, it will complain the above the warning message.

   This issue can be fixed by adding the boot option of "acpi.power_nocheck=1"
since the 2.6.28 kernel.

   Please try it and see whether it still exists. Thanks
