Hi Fabio. I wrote some GPE fixes for my Asus laptop and they need some wider testing :-). I think I found why we get GPE storms and how to deal with them. I posted them on the lists a series of three patches, but I neglected to CC any potential testers. For convenience I squished them into a single patch and posted them in Bugzilla. My bug: Patch: The risky part of the fixes removes the GPE interrupt storm check and the GPE polling mode. So you won't see the "disabling EC GPE" message, and I'm hoping this will stop g-p-m misbehaving for you. I'm not sure what could happen if it's broken somehow :-). If you have ACPI hotkeys (i.e. running acpi_listen shows events when you press hotkeys), please check they still work. If not, you should have at least one button that generates an ACPI event - the power button. So it would be great if you could check the power button still works as normal. (On my computer, g-p-m handles the power button and pops up a logout/shutdown prompt).
