Hi, 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) and 'Bluetooth: avoid silent hci_bcm ACPI PM regression' (commit 4294625e029028854596865be401b9c5c1f906ef) building the kernel now needs
CONFIG_SERIAL_DEV_BUS=y CONFIG_SERIAL_DEV_CTRL_TTYPORT=y CONFIG_BT_HCIUART_BCM=y in the config to keep sound and BT working on Intel Atom devices. Currently the config used to build experimental package linux-image-4.15.0-rc5-amd64 (4.15~rc5-1~exp1) doesn't include them. Any chance of including these in the config going forward? Regards, Ian
