Aht10k-ct: ATH10K_DBG_BUFFER in kernel logs

I'm testing the ath10k-ct firmware, so far so good (didn't do in-depth tests). Wifi is stable, no crash, no error in logs, just an annoying debug messages

I'm getting a bunch of the following in the Kernel Log: ath10k_pci 0000:01:00.0: ath10k_pci ATH10K_DBG_BUFFER

Here are the installed packages:

root@router router# opkg list-installed | grep ath
ath10k-firmware-qca99x0-ct - 2017-01-11-ab432c60-1
kmod-ath - 4.4.42+2016-10-08-1
kmod-ath10k-ct - 4.4.42+2017-01-10-f5bacb83-1

How can we silence these messages? Is it an indication of a problem?

Tested using 17.01-rc1 and a Tp-Link C2600

Off-topic Q, for basic AP usage, is there any advantage of using the CT firmware instead of the default one?

And how do you use the CT firmware? Just opkg remove the non-CT version and opkg install the CT version?


Edit: There is a similar thread not long ago: Experience with ath10k CT firmware/driver vs original firmware/driver

For installing that's pretty much that remove one and install the other one.

Apparently there is some goodies w/ the CT version, but for me it was mostly for sake of testing, since we are trying to test 17.01.0-rc1.

Here is the page for the CT firmware =>


I am seeing the same issue. ath10k-firmware-qca99x0-ct and kmod-ath10k-ct generated a lot of ATH10K_DBG_BUFFER messages in dmesg. I don't know any solution to disable them yet.
