[LEDE-DEV] LEDE Reboot r1588+145 vs LEDE Reboot r1588+257 on TP-Link Archer C7 v2 / constant bootloop on 257

[Břetislav Kubesa]

Hi,

so I found out bootloop is caused by activation of Qualcomm Atheros 
QCA9880 802.11nac (radio1) - 5 GHz wireless.

I tried using QCA988x firmware as well as the CT modifications, but 
still it seems that with activation of ac radio, router goes to boot-loop.

CONFIG_PACKAGE_ath10k-firmware-qca988x=y
CONFIG_PACKAGE_ath10k-firmware-qca988x-ct=y

So is the ath10k-firmware-qca988x broken maybe ?

Related config :

config wifi-device 'radio1'
     option type 'mac80211'
     option hwmode '11a'
     option path 'pci0000:01/0000:01:00.0'
     option htmode 'VHT80'
     option country 'US'
     option channel 'auto'
     option txpower '30'

config wifi-iface
     option device 'radio1'
     option network 'lan'
     option mode 'ap'
     option key 'password'
     option ssid 'aparcher'
     option encryption 'psk-mixed+ccmp'

Confirmed on LEDE Reboot r1588+365  as well.
