Cool, now I'm using current linux 2.6.26-rc8 from git b8a0b6ccf2ba2519ace65d782b41ee91bf3c3778 Now I'm reaching 9.8w consumption :-) Really good improvements. btw, any plans to move some of the powertop features to acpid ? I mean, the wireless pm for iwl4965 could be there, couldn't it ? I'll anyways clone linux-acpi tree and try to test recent patches as much as I can, although omap is really eating my time. thanks again Arjan. -- Best Regards, Felipe Balbi felipebalbi@xxxxxxxxxxxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
