See >><http://bugzilla.kernel.org/show_bug.cgi?id=3534> for that discussion. I just tried the first failing commit (02b28a33aae93a3b53068e0858d62f8bcaef60a3): Author: Len Brown <[EMAIL PROTECTED]> Date: Mon Dec 5 16:46:36 2005 -0500 [ACPI] Enable Embedded Controller (EC) interrupt mode by default "ec_intr=0" reverts to polling "ec_burst=" no longer exists. Signed-off-by: Len Brown <[EMAIL PROTECTED]> Acked-by: Luming Yu <[EMAIL PROTECTED]> but with the vanilla (BIOS 1.11) DSDT. And not only did S3 sleep happen, but the thermal+processor bug didn't show up: i.e. it did two (actually) many S3 sleep-wake cycles. So the problem is due to something in the modified DSDT, which is either a problem itself or it exposes another problem. [Picture of me hanging head in shame for putting people to the trouble.] My only excuse is that long ago (2.6.11), the machine wouldn't S3 sleep at all with the vanilla DSDT, and I patched it as recommended by the ACPI experts. However, the current ACPI interpreter seems to handle the 600X's mangy DSDT. Now I agree 100% with Len Brown that it's best to have ACPI handle marginal DSDT's, not hack the DSDT. -Sanjoy `Never underestimate the evil of which men of power are capable.' --Bertrand Russell, _War Crimes in Vietnam_, chapter 1. ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
