Let me go queue both of these series now, thank you so much for these. Also, I would like to formally apologize that you had to do this work on no notice at all. I, and others, have been asking Intel to allow you to be involved in this type of thing for many many many months. Despite their assurance of "we got this", the obviously did not follow through at all, and you and all Debian users suffered as a result. thanks, greg k-h
