I would recommend you file a bugzilla at https://bugzilla.redhat.com even if you are not a customer. This is a bug report, not a support request. We contribute upstream by reporting bugs. :-) Speaking of a sata_sil-related bug, there used to be one as seen in this CentOS bug tracker: http://bugs.centos.org/view.php?id=3165 The CentOSPlus kernel had a fix for it for years until it was eventually fixed upstream: https://bugzilla.redhat.com/show_bug.cgi?id=640586 Akemi
