Dear Kalle,

I tried the latest firmware available on your github account for
IPQ8074 on my Xiaomi AX6 router, and it produces a firmware crash
right after the Q6 processor tries to boot:

Kernel is 5.15.71
ath11k is almost up to date (I believe only the last 2 or 3 commits
are missing compared to 'ath-next')

I also tried with firmware 2.6.0.1-00861, it yields the same firmware crash.

Firmware 2.5.0.1-01208 is the last one that works properly.

There are others who also experience the same firmware crash with the
same device.

Can you please help us with this?

Regards,
Csaba
