Public bug reported: We're running Ubuntu 20.04.1 LTS We're expecting the RTL8822BE to have bluetooth working after boot We're not expecting the RTL8822BE to attach bluetooth, disconnect shortly, then become attach after resuming from a suspend.
My ThinkPad is equiped with the RTL8822BE chipset that's providing WiFi and, should, Bluetooth. The WiFi portion of this works fine, however the Bluetooth portion is acting unusual. It will detach itself during boot then after resuming from a suspend it'll become reattached and stay attached until the system is restarted. In brevity: with dmesg, during boot it sees there's a USB device [1.270947] usb 3-1: new full-speed USB device number 2 using xhci_hcd Then later detects what it is [ 1.447016] usb 3-1: New USB device found, idVendor=0bda, idProduct=b023, bcdDevice= 1.10 [ 1.447019] usb 3-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 1.447022] usb 3-1: Product: Bluetooth Radio [ 1.447024] usb 3-1: Manufacturer: Realtek [ 1.447025] usb 3-1: SerialNumber: [...] Then later it disconnects after thinkpad_acpi starts working [ 23.347846] thinkpad_acpi: ThinkPad ACPI Extras v0.26 [ 23.347849] thinkpad_acpi: http://ibm-acpi.sf.net/ [ 23.347850] thinkpad_acpi: ThinkPad BIOS R0UET76W (1.56 ), EC R0UHT76W [ 23.347850] thinkpad_acpi: Lenovo ThinkPad E585, model 20KVCTO1WW [ 23.351660] thinkpad_acpi: radio switch found; radios are enabled [ 23.351693] thinkpad_acpi: This ThinkPad has standard ACPI backlight brightness control, supported by the ACPI video driver [ 23.351693] thinkpad_acpi: Disabling thinkpad-acpi brightness events by default...
