--- Comment #55 from Ben Adler (ben.adler.hh@googlemail.com) ---
My AX200 based blueooth hasn't worked on my arch linux for a while (with the
same errors), but cannot say at which kernel version change exactly it broke.
Just updated my arch linux to kernel

6.7.0-arch3-1 #1 SMP PREEMPT_DYNAMIC Sat, 13 Jan 2024 14:37:14 +0000 x86_64
GNU/Linux

and it's still broken. Inspired by Arjans answer, I downloaded
linux-firmware-20230323.gitbcdcfbcf from some ubuntu package, and did a

mv -i ibt-20-1-3.sfi ibt-20-0-3.sfi /lib/firmware/intel/

and it works again!

Here's the broken arch firmwares:
f22358f118acb67b26cb8cac8443e09a  ibt-20-0-3.sfi.zst
f22358f118acb67b26cb8cac8443e09a  ibt-20-1-3.sfi.zst

Here are the working ubuntu gitbcdcfbcf firmwares:
# md5sum ibt-20-1-3.sfi ibt-20-0-3.sfi
dda190be754f26625955b73f05fc2ba2  ibt-20-1-3.sfi
217eaf48a8a825b2f95fd49c241188f5  ibt-20-0-3.sfi

Hope this may help somebody.
