FWIW: They are generated several times during every startup of the machine:

sudo journalctl -b | grep radio_led
718:Okt 31 11:46:21 gruenix kernel: leds fujitsu::radio_led: Setting an
LED's brightness failed (-2147483648)
744:Okt 31 11:46:22 gruenix kernel: leds fujitsu::radio_led: Setting an

893:Okt 31 11:46:29 gruenix kernel: leds fujitsu::radio_led: Setting an
LED's brightness failed (-2147483648)

But, yes. This is only a cosmetic issue. There don't seem to be too many
people reportig this as well.

Greetings
Harvey
