ath11k-qca crashing

[André Eberle]

I have attached the dmesg. It is the UART dump essentially, so it
includes some pre-boot info, maybe it is useful:

There is no stack trace dump during the crash, unfortunately. As you
can see the system suddenly reboots (sometimes it just freezes).

I have added the logread from openwrt also. This one has trace-level
messages from dmesg, so maybe it is more helpful. I enabled maximum
debug level for ath11 on this one, hope it helps:

echo 0xffffffff > /sys/module/ath11k/parameters/debug_mask
