Since the Tumbleweed/KDE upgrade to v 20220128 and now 20220201 the boot shows six lines with the error message in the title of this thread. I dont need bluetooth (at least at the moment) but I wonder what is wrong because these messages never showed up before. The command journalctl -b 0 | grep Blue shows the following:

Since everything works fine there is no urgency. In the Arch Linux forum (https://bbs.archlinux.org/viewtopic.php?id=273098) I found '“The messages are caused by a bug in kernel 5.16.0” so I guess the easiest way is just wait until the next kernel update is due
