[ACPI] kacpid 100% CPU when lid closed

[Alexey S. <le...@ne...>]

Hello,

I have a Dell 2650. Whenever I close the lid, the GPE code starts handling massive amounts of L1D events, which yields the CPU usage.
This problem started with kernel 2.6.5. Right now, I'm running 2.6.8-pre3 with the latest ACPI patches. There have been several messages 
from end-users to LKML about this. Please refer to mine for some profiling results and traces:

The first message from May, 2004 is here:

It would be wonderful if a knowledgeable person could give some suggestions, or even fix it (I'm happy to help, just tell me how).
I'm quite tired of living in the stone age of 2.6.3 :)

Thanks a lot!
