Please see: http://www.flickr.com/photos/zrr/4118682747/ and http://www.flickr.com/photos/zrr/4119453092/ I makes no difference if I choose ATA or only IDE. I am also attaching you my Kernel .config I could also test with 2.6.32-rc8 (torvalds-git) I suggest you send me two .config that I can both test with 2.6.31.6 Thank you for your Feedback. Best Zeno
