Title:
RTL8822BE ThinkPad E585, Bluetooth detaches on boot, attaches after
suspend
Status in linux package in Ubuntu:
Incomplete
Bug description:
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

Then later it disconnects after thinkpad_acpi starts working

So either thinkpad_acpi is doing something that triggers the bluetooth
to disconnect (since it always seems to disconnect after
thinkpad_acpi) or something else is going wrong.
apport-collect will follow shortly.
