This is an upstream regression, that could be fixed with the next version: https://lore.kernel.org/all/CABBYNZL0_j4EDWzDS=kXc1Vy0D6ToU+oYnP_uBWTKoXbEagHhw@mail.gmail.com

Could you please backport the patch before 6.11.5 releases?

Bluetooth is likely broken for all devices with 6.11.4. Every device needs a reconnect after boot and after suspend/resume. I've an Atheros and in the forums people with MediaTek also report.

I wonder how the managed to release this.
