Description:
I have upgraded the kernel to 6.3.6 and the Bluetooth adapter does not work with dmesg below:
[ 222.064050] Bluetooth: hci0: ACL packet for unknown connection handle 3804
[ 222.064082] Bluetooth: hci0: ACL packet for unknown connection handle 3804
[ 222.064087] Bluetooth: hci0: ACL packet for unknown connection handle 3804
[ 222.064090] Bluetooth: hci0: ACL packet for unknown connection handle 3804

When it was initialized, this message appeared:
[ 6.771121] Bluetooth: hci0: HCI Enhanced Setup Synchronous Connection command is advertised, but not supported.

Now I can't use Bluetooth at all.

Kernel version: 6.3.6-arch1-1
Device info: Foxconn / Hon Hai Bluetooth Device, 0489:e0df

Thanks!

If it previously worked, it's a kernel regression. Usual advice for debugging kernel regressions is here [1]. It's not an Arch packaging bug. You might have to report upstream to the kernel folks. Please let us know what you find out.
