First, we should check for the possibility of a kernel or userspace issue that is getting in the way of the bluetooth firmware loading when a microcode update is available to be applied... Hopefully, this should be easy enough to do: intel-microcode package 3.20151106.1 is reported to work, so it is just a matter of testing successive intel-microcode packages, and looking at the full logs of the attempts. Please report the contents of /proc/cpuinfo with the latest intel-microcode package that works, and /proc/cpuinfo with the package that doesn't (3.20170707.1~ubuntu16.04.0). Also, please report the output of "dmesg" or from "journalctl -k -b" (i.e. the kernel logs) in the failure case, so that we can search for some sort of kernel message by the bluetooth stack, etc. You could test when the breakage happened using the Debian packages, They should be 100% compatible with the Ubuntu OS, as far as I know. Packages to test (in order, you can stop when the breakage disappears): http://snapshot.debian.org/package/intel-microcode/3.20170707.1/ http://snapshot.debian.org/package/intel-microcode/3.20170511.1/ http://snapshot.debian.org/package/intel-microcode/3.20161104.1/ http://snapshot.debian.org/package/intel-microcode/3.20160607.2/ Thanks. -- Henrique Holschuh -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1700373 Title: intel-microcode is out of date, version 20170707 fixes errata on 6th and 7th generation platforms To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/intel-microcode/+bug/1700373/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
