Hi,

With the firmware from linux-firmware and vendor SDK, ath11k used to work on kernel v5.19-rc6 but it is now failing on kernel v6.2-rc1.

dmesg of the failure with firmware from linux-firmware:

Host platform is Thundercomm T55 board based on Qualcomm SDX55 SoC (ARM32).

Vendor SDK firmwares are not supported. So to keep things simple please just use files from linux-firmware.

I have not heard anyone reporting new issues with QCA6390, also my daily driver laptop has QCA6390 and I'm running v6.2 + latest wireless on it right now. And the error message comes very early during the firmware boot process, which makes me wonder if it's a lower level problem somewhere in some other module. Any chance of bisecting the issue? I can't think of much else to do at this point.

Also verifiying that the firmware files are not corrupted is a good idea, can you show md5sum listing?

mani, what's the status of this? I'm tracking this and I wonder if I can stop doing so.

Hi Thorsten,

Looks like mani ignore this regression for now.
