This has been already reported in *[PATCH] Bluetooth: Apply initial 
command workaround for more Intel chips* [1].

As I replied there, on what device do you experience this, and how can 
it be reproduced?

I have a Dell Latitude E7250 with the Bluetooth device 0x0a2a, and 
everything works fine under Debian sid/unstable with Linux 5.15 up to 
5.16-rc6.

     Bus 002 Device 003: ID 8087:0a2a Intel Corp. Bluetooth wireless 
interface


Kind regards,

Paul
