            Bug ID: 217805
           Summary: Qualcomm NFA725A on T14s AMD Gen3: Bluetooth: hci0:
                    Failed to send headers (or body or access otp area)
           Product: Drivers
           Version: 2.5
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P3
         Component: Bluetooth
          Assignee: linux-bluetooth@vger.kernel.org
          Reporter: fanf42@gmail.com
        Regression: No

Hello,

(Sorry by advance if it's not the correct place to discuss that, but I tried
other place like my distro kernel forum
(https://bbs.archlinux.org/viewtopic.php?id=286929), interactive chat, etc and
nobody was able to help).

[1] == Short summary ==

I have a lenovo T14S AMD Gen 3 with a *Qualcomm NFA725A* Wi-Fi card (which is
actually reported by lspci as QCNFA765) and bluetooth never worked on it,
failing to load the rampatch with "failed to send header" or "failed to send
body" or "Failed to access otp area (-71)".

Other people reports bluetooth as working
(https://wiki.archlinux.org/title/Lenovo_ThinkPad_T14s_(AMD)_Gen_3) and a work
friend has a T16 AMD gen1 which seems to have exactly the same chipset and work
flowlessly. So perhaps it's an hardware issue, but I don't know how to qualify
it if so.

=> How can this be further qualified/debuged/workarounded?

Any help, even RTFM pointing to corresponding manuals would be very much
appreciated.


[2] == logs and more details ==

I have that laptop since october 2022 and use archlinux with the standard
kernels. None made bluetooth wroked since then. First install was around linux
6.0.10 and current kernel: 6.4.10-arch1-10.

There is nothing obvious in bios setting that could lead to that (bluetooth is
enabled).
