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.
=> 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, starting around
linux 6.0.10 and current kernel: 6.4.3-arch1-2.
There is nothing obvious in bios setting that could lead to that
(bluetooth is enabled).
