On Linux Mint have just encountered issue and confirmed is urfkill on
27/05/2018. Fan going nuts, cpmputer at a crawl, 'top' showed 100% CPU
from urfkilld.
I suspected something was off for quite a while. I believe the this
softwarealso led to a number of crashes and loss of unsaved data.
Problem still exists on a Dell Inspiron 6500 after upgrading to 16.04.3
LTS.
The workaroundscript in /lib/systemd/system-sleep/urfkill works for me.

@nacer I'm not sure I understand what you mean. The script I posted
tells urfkill service to restart after resume to stop using too much
CPU.
FWIW, restarting urfkill manually always fixed the CPU issue for me. The
script only helps doing so after resume.

The old workaround for pm-utils doesn't work anymore in vivid since pm-
suspend is never run. Now systemd-sleep is used instead, so you'll have
to put the following script in /lib/systemd/system-sleep/urfkill:

I've upload a copy of urfkill in my PPA for testing... Indeed I don't
currently have a better solution, aside from disabling the input handler
altogether on these systems -- unless it was to be reopened later, but
this is a more involved change.
Please try https://launchpad.net/~mathieu-
In urf-input.c, there's a line
if (condition G_IO_IN) {
which needs to be
if (condition G_IO_IN !(G_IO_ERR | G_IO_HUP)) {
This is because the actual condition passed to the function after
suspend/resume and consequent new inode # for /dev/input/event4 is
(gdb) p condition
$2 = (G_IO_IN |
Great, thanks for figuring this out!
And yes, unfortunately urfkill still has a lot of rough edges, but
that's why there was a call for testing.
I will add a patch for this case in the morning.

The workaround works for me (with Dell XPS Developer Edition).
Regarding what's actually happening, it looks like after suspend/resume
the input device used by urfkill (in my case, /dev/input/event4) comes
back with a different inode number, so that the file descriptor held by
urfkill is invalid,
