This is mainly to acknowledge that I have read this email. Since my Fujitsu does not have any LEDs I do not have any direct experience with their use within the driver. The existing LED code was contributed by others and recently modified by Michal's patches as part of a broader tidy up of the driver. I'm more than happy for Michal to take the lead in investigating this since I think he has a Fujitsu with LEDs. > > I am using archlinux and as of kernel > > 4.11 (IIRC) there has appeared an error message in the journalctl log > > saying: > > > > kernel: leds fujitsu::radio_led: Setting an LED's brightness failed > > (-2147483648) > > > > This appears for several times: > > > > harvey@gruenix ~/Documents/scripts $ sudo journalctl -b | grep radio_led > > 725:Jul 14 12:29:37 gruenix kernel: leds fujitsu::radio_led: Setting an > > LED's brightness failed (-2147483648) > : > 4.11 included a patch which sets the default trigger for the radio LED > to rfkill-any, which would explain why you only started seeing these > errors after upgrading to that version.

How does it behave under other operating systems? Also, how did these LEDs behave under earlier Linux kernel versions? In other words, is the non-functionality of these LEDs a regression in 4.11, or have they never worked on your laptop? Regards jonathan
