Re: Failed to start radar detection: -22 (Invalid argument)

[Jeremias Blendin <jeremias@blendin.org>]

Hi,

I switched to Arch LInux and added this to the configuration of my
custom kernel:

# cat config.x86_64
...
CONFIG_CFG80211_CERTIFICATION_ONUS=y
CONFIG_ATH_REG_DYNAMIC_USER_REG_HINTS=y
CONFIG_ATH_REG_DYNAMIC_USER_CERT_TESTING=y

However, I still have the same issue:
