I'd even forgotten having reviewed and added a line or two to that patch .. if I lost my archives I'd probably have no memory left at all :) This post: http://lists.freebsd.org/pipermail/freebsd-acpi/2008-February/004521.html points to this PR: http://www.freebsd.org/cgi/query-pr.cgi?pr=bin%2F120336&cat= which was closed with reference to this post: http://docs.FreeBSD.org/cgi/mid.cgi?1203126071.833.19.camel Useless trying to apply anything like this to recent powerd sources, though. Good luck with getting its fan to go, or a warranty claim! cheers, Ian _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-mobile To unsubscribe, send any mail to "[email protected]"
