Public bug reported:
With kernel 4.4.0-119-generic on Ubuntu 16.04.4 LTS (xenial) x86_64 and
included intel_hid driver (which seems to be responsible for the key
events), I get the following report when pressing the function key
Fn+PrtScr which is supposed to trigger the wifi blocking state using
rfkill interface via urfkilld daemon:
Apr 17 19:02:45 aton kernel: [ 387.963583] urfkilld[3119]: segfault at 18 ip
000055948349f46b sp 00007ffd26296730 error 4 in urfkilld[559483495000+19000]

disappeared from the bus
Apr 17 19:02:46 aton kernel: [ 388.137360] rfkill: input handler enabled
Apr 17 19:02:46 aton kernel: [ 388.418242] rfkill: input handler disabled
Apr 17 19:02:46 aton NetworkManager[1099]: <info> [1523984566.3369] urfkill
appeared on the bus
It seem that urfkilld crashes and gets restarted by systemd or similar.
Nothing happens to the Wifi button state which can be shown via
rfkill list
0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
1: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
Another oddity is that the urfkill package in all Ubuntu versions is
0.6.0~20150318.103828
but upstream websites have
0.3.0 (https://www.freedesktop.org/wiki/Software/urfkill/)
0.5.0 (https://github.com/lcp/urfkill/releases)
only. Seems like almost abandoned software to me.
Since this was a distribution upgrade, I purged and reinstalled the
package but without effect.
Any ideas?
