Bluetooth errors on boot

Hello,
some time ago, I started noticing errors regarding to bluetooth on  boot:

Jun 16 13:18:44 Samo-PCTP kernel: Bluetooth: hci0: Reading supported features failed (-16)
Jun 16 13:18:44 Samo-PCTP kernel: Bluetooth: hci0: Setting Intel telemetry ddc write event mask failed (-95)

This happens every  time I turn on my computer but not when I restart it. Example: My computer is turned off for 2 days and when I boot it, this error pops out. However, when I restart after update, no errors regarding to the bluetooth are present.

What I found is an article on github which says about the firmware problem with bluetooth. However, I have not found same information anywhere else: https://github.com/torvalds/linux/commi … 2c5b4b7167

Anyone is able to help me/has some information about it?
Thank you

Thank you,
however, disabling "runtime-pm" module did not work. It could not even find the module.
Sending my dmesg for more information. Looks like it can load the module, but has problems once it tries reading the supported features:

Re: Bluetooth errors on boot

The secure boot is enabled , it could interfere with device drivers
Try to deactivate it by the BIOS menu and then see if the problem persist.
Btw i didn't undesrstood if you are having problems with bluetooth? Or  if that error message not interfere with normal bluetooth operation

Bluetooth itself works fine, will check the bios tomorrow. Just the errors pop out on a boot.

I advise you not to risk wasting time and taking risks to resolve error messages that do not affect the regular functioning of the bluetooth.
Btw probably after disabling the secure boot these error will not appear anymore

I checked the secure boot option - it was turned off all time and makes zero impact on the behaviour..

Re: Bluetooth errors on boot

Turns out what was wrong for me was that the Bluetooth module wasn't loading correctly on a cold start so I didn't have any issues when starting and then rebooting.
What then worked for me was forcing it to load early by editing/creating the modules file so:

sudo vim /etc/modules-load.d/bluetooth.conf

and then adding

btusb
bluetooth

into it.
Afterwards you'll have to regenerate the initramfs by running

mkinitcpio -P

as a superuser (sudo).
This solved the problem for me so I hope it can help you even if I'm a bit late to this post
