#15 says problem went away but is on Kernel 4.4 and Kerne 4.8 where message was "hacked" to not display. With kernels 4.9, 4.10, etc. the message reappears as per bug report here: https://bugzilla.kernel.org/show_bug.cgi?id=193531
#17 closing this bug based upon #15 should be reconsidered. Also note this bug is a duplicate of: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1690502 which has fewer subscribers but more accurate information. There is a third duplicate bug report in launchpad which I don't have the link for just now. ** Bug watch added: Linux Kernel Bug Tracker #193531 https://bugzilla.kernel.org/show_bug.cgi?id=193531 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1584407 Title: ACPI Error: [\_SB_.PCI0.XHC_.RHUB.HS11] Namespace lookup failure, AE_NOT_FOUND (20150930/dswload-210) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1584407/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
