I am having a similar issue with Intel 8260. Wifi and BT works correctly after cold boot. Wifi works correctly after suspend, but BT was showing no adapters available in KDE plasma widget. dmesg would report "[ 150.064149] Bluetooth: hci0: Failed to send firmware data (-38)" after each resume.
My 8260 was not listed in lsusb, but is listed in lspci. Fix in #47 did not work for me. However, adding a systemd service to rmmod and modprobe btusb after each resume seems to have the BT adapter working correctly now. uname -a: Linux uranus 4.18.0-13-generic #14-Ubuntu SMP Wed Dec 5 09:04:24 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1790454 Title: Bluetooth (btintel) stops working after suspend/resume To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1790454/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
