Public bug reported: After the mainline kernel was patched with 'serdev: Add ACPI support' (commit 53c7626356c7584e82510d86394a6dcd80525614) and 'serdev: enable TTY port controller support by default' (commit 22b276a4072087e7b7f1723ccd8a1aa18fab8bbf) and 'Bluetooth: hci_bcm: Add serdev support' (commit 33cd149e767be9afbab9fcd3d5165a2de62313c8) the mainline kernel the config needs CONFIG_SERIAL_DEV_BUS=m changing to CONFIG_SERIAL_DEV_BUS=y and CONFIG_BT_HCIUART_BCM=y to keep sound and BT working on Intel Atom devices.
Currently the latest Ubuntu config for 4.15 (see 0006-configs-based-on- Ubuntu-4.15.0-2.3.patch) still only has CONFIG_SERIAL_DEV_BUS=m The config needs to be update to take into consideration the implications of the aforementioned patches together with the settings identified. ** Affects: ubuntu Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1739939 Title: Update Ubuntu-4.15.0 config to support Intel Atom devices To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1739939/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
