FS#2102 - ipq806x: ath10k-firmware-qca9984-ct crashes system

Supply the following if possible:
- Device problem occurs on

 tplink-c2600
 netgear-r7800

- Software versions of OpenWrt/LEDE release, packages, etc.

 18.06.2

- Steps to reproduce

 opkg remove ath10k-firmware-qca9984 && opkg install ath10k-firmware-qca9984-ct

On both systems using the -ct firmware caused a crash of the router resulting in a reboot. Replacement of the ct with the standard firmware makes the routers stable again.

No crashlogs haven been found (no persistent logging).

Hmm, the ath10k-firmware-qca9984-ct requires the special kmod-ath10k-ct driver as well. Can you please test what happens if you also install the ath10k-ct driver?

Small correction to the bug report:
with tplink-c2600 concerns ath10k-firmware-qca99x0-ct
with netgear-r7800 concerns ath10k-firmware-qca9984-ct

About need to install ath10k-ct driver: according to the package description only the ct-htt firmwares require the installation of the ath10k-ct driver.

~/ # opkg list |grep -e "qca99.*-ct.*"

I'll retest the ct firmware on the netgear-r7800 and will report on that.

Running on R7800 now more than 10 days without any problem with CT firmware and non-CT driver. This environment has only few concurrent WiFi users, so maybe the problem only occurs with larger number of users. No suitable environment available though to test this.
