Bluetooth: hci0: Failed to load rtl_bt/rtl8821a_fw.This package contains the files needed for installing the WLAN PCI Express driver. I still get the same error messages, i.e.: I recompiled my kernel and loaded the following modules at boot-time: Thanks for your help! I'm afraid it wasn't a module vs built in the kernel issue. I never had any trouble with Wifi/Bluetooth mini-Pci devices.

Your wifi module do not have any parameter for Bluetooth coexistence. In plus, for Bluetooth, I enable every option of the section. Support in the kernel image need to have the firmware files in the image too and modules in intiramfs need to have the firmware files in the initramfs too. You can see the problem I am talking about in the output So, because modules are in the root filesystem like firmware files, when the kernel load a module, the firmware file are available too if they are emerged. Bluetooth support is not mandatory to be in the kernel image unless an option have only this choice in which case, I accept it. What I do for the kernel configuration is to put everything not mandatory to be in the kernel image as modules. This can lead to a probe fail unless you put the firmware files in the kernel image too or in an initramfs. If your kernel probe the Bluetooth devices before the real root partition is mounted, the firmware files needed will not be available. config, any Bluetooth option you enable is in the kernel image. Is there some configuration I need to do?įrom your. I just installed linux-firmware & restarted but I still get the same error. You have installed linux-firmware package?
