Patch 1 rejects against the latest git tree, due to Len's latest ACPI changes. That (and possibly patch 4) need redoing. >>From a first look, these patches look ok to me, so if you rediff these, and Len is happy with the ACPI changes, I'm happy to merge them for 2.6.14 Thanks, Dave ------------------------------------------------------- SF.Net email is Sponsored by the Better Software Conference & EXPO September 19-22, 2005 * San Francisco, CA * Development Lifecycle Practices Agile & Plan-Driven Development * Managing Projects & Teams * Testing & QA Security * Process Improvement & Measurement * http://www.sqe.com/bsce5sf
