I've been tracing the cause of keventd sometimes sucking all available CPU after a suspend-to-disk (2.4.22). It seems that the embedded controller in my Omnibook continally generates interrupts iif an ACPI event occurs at the wrong time during the cycle (I haven't determined when the critical time is yet). I'm therefore wondering if there is a method whereby it can be reset or otherwise made to return to its normal state. I'm particularly noticing this when a lid event occurs during suspend, whether or not button.o is insmod'd. If acpid is running, it shows thousands of lid events per second. Another swsusp user has reported similar issues. Regards, Nigel -- Nigel Cunningham 495 St Georges Road South, Hastings 4201, New Zealand Evolution (n): A process whereby infinitely improbable events occur with alarming frequency, order arises from chaos, and no one is given credit. ------------------------------------------------------- This SF.net email is sponsored by: SF.net Giveback Program.
