Anyone have any ideas on the below? Assuming it's related to the bug previously mentioned (http://bugzilla.kernel.org/show_bug.cgi?id=6612) which it might not be at all, it looks like the accepted patch in the bug report is clearing an ACPI event which should never get generated in the first place? If so, could the same thing be happening here? > I have a Samsung R560 laptop running amd64 Debian testing with a > 2.6.29.3 kernel compiled from vanilla sources.
