Intel AX200 Bluetooth does not work with 6.8.2 and util-linux 2.40

Description:

Yesterday, I upgraded to linux 6.8.2.arch1-1 and util-linux 2.40 which broke my Intel AX200 Bluetooth. Downgrading to 6.8.1 and 2.40rc2 makes it work again. A few people on the ArchLinux subreddit have also reported similar issues with the new packages. This also seems to affect linux-lts 6.6.23-1.

Additional info:

package version(s): linux 6.8.2.arch1-1 and 6.6.23-1, util-linux 2.40-1

link to upstream bug report, if any: There seems to be some chatter about this issue here: https://lore.kernel.org/lkml/08275279-7462-4f4a-a0ee-8aa015f829bc@leemhuis.info/T/

Seems to be roughly similar, but I do not have the technical expertise to say with any amount of certainty.
