How to disable dmesg bluetooth spam bug until 5.16.5

Hello,

there seems to be a bug [1,2] with kernel 5.16.4 which spams

in dmesg.

I use dmesg to read out information about various USB Hardware which I’m testing here at work, so I use it a lot atm.
My only solution is to disable bluetooth which disconnects my headset, or grep dmesg output every time I connect a new device,
dmesg --follow is much faster.

Someone has an idea how to disable the spam? Hopefully 5.16.5 in dup soon.

Thanks.

Hi! Welcome to forums!

One option is to use the --level option to dmesg. Another option is to boot the previous kernel through extended options in GRUB. A default TW installation keeps installed the current and the previous one.

Thanks for the tips. Just for information, the dup to 5.16.5-1-default #1 SMP PREEMPT Thu Feb 3 05:26:48 UTC 2022 (1af4009) x86_64
x86_64 x86_64 GNU/Linux today fixed the issue.
