Sorry I took so long to respond; I work for Comcast and the Super Bowl is a very busy time here. I asked the guy who built the kernel what specs he modified, and he directed me to the "kernel-lt-4.4" and "kernel-ml-4.10" specfiles. He says the 4.9-lt (the one I'm having issues with) is a combina= tion of the two, so I uploaded a diff with each of them. I'm not totally sure how helpful that is, so if you want a diff with a specific, standard kernel just let me know. --=20 You are receiving this mail because: You are the assignee for the bug.
