Thanks for posting this, it fixes my EHCI + APIC error, and makes my laptop work just fine. Turns out that 2.6.14 worked for it, but 2.6.15 didn't. git bisect a zillion times later narrowed it down to the usb early handoff stuff but due to merge issues, it was tough to track down the exact patch. For fun I tried this one on top of the latest -mm, and it works! So, care to clean it up to make it feel better to you and send it to me again so I can add it to my tree? I know the next SuSE kernel will need it :) thanks, greg k-h ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
