customized DSDT: don't send notification in _STA method

Michal,
could you please try this customized DSDT?
how to override a DSDT can be found at
http://www.lesswatts.org/projects/acpi/overridingDSDT.php
After recompiling the kernel, please boot with acpi.debug_level=0x0f
and attach the dmesg output after S3.
Please use this DSDT and do the same test on an old/working kernel.

thomas,
I think I met a similar problem on a HP laptop.
there is a endless loop while resuming from S3,
1. dock device is notified to recheck it's status
2. dock driver evaluate _STA method.
3. a notification is sent when evaluating _STA.

I don't know why this is a regression.
Maybe MIS5 and local2 have different values when using the new dock driver?
