[1.] One line summary of the problem:
Error accessing realtime clock

[2.] Full description of the problem/report:
I was running a script previously that uses rtcwake which has since
stopped working. The script automatically hibernates my laptop after a
set period of time in sleep mode, and was working perfectly in kernel
4.10.0-37.

In the process of troubleshooting, I discovered that the problem was
with rtcwake which is complaining about /dev/rtc0 missing.

Here is output from a sample rtcwake command:

peter@haven:~$ rtcwake -m no -s 1300
rtcwake: assuming RTC uses UTC ...
rtcwake: /dev/rtc0: unable to find device: No such file or directory

I verified that in fact, that directory is missing.

I get the following RTC messages in dmesg when I boot the current
kernel:

peter@haven:~$ dmesg | grep -i rtc
[ 0.089393] RTC time: 17:03:55, date: 11/01/17
[ 1.238784] rtc_cmos 00:01: RTC can wake from S4
[ 1.238794] rtc_cmos: probe of 00:01 failed with error -16
[ 1.295459] hctosys: unable to open rtc device (rtc0)

In researching the error, I found some suggestions to get further
information with timedatectl and hwclock, so here are the results from
those commands as well.

Output of timedatectl:

peter@haven:~$ timedatectl
      Local time: Fri 2017-10-27 19:06:26 EDT
  Universal time: Fri 2017-10-27 23:06:26 UTC
        RTC time: n/a
       Time zone: America/New_York (EDT, -0400)
 Network time on: yes
NTP synchronized: yes
 RTC in local TZ: no

Output of hwclock --debug:

peter@haven:~$ sudo hwclock --debug
[sudo] password for peter:
hwclock from util-linux 2.30.1
Trying to open: /dev/rtc0
Trying to open: /dev/rtc
Trying to open: /dev/misc/rtc
No usable clock interface found.
hwclock: Cannot access the Hardware Clock via any known method.

More evidence to suggest this is a kernel bug: I live-booted a copy of
Antergos Linux, which was using the Arch kernel 4.14.12-1-ARCH and it
exhibited the same problem with the real time clock as Ubuntu 17.10.

Hi Alexandre,

I still see the same symptoms under the new kernel.  I've copied some
info below.  While I am still running this kernel, is there anything
else from my system that would help you?

I've uploaded
https://bootlin.com/~alexandre/linux-image-4.16.0-rc1+_4.16.0-rc1+-32_amd64.deb

This should output much more debug before the failure.

Can you also join your /proc/iomem and /proc/ioports files.

So I can tell you what is happening but I can't tell you why. You have a
watchdog at 0x70 (size 2) and the RTC at 0x70 (size 8).

Because the watchdog driver is probed first and it requests the io
region, when the RTC driver is probed, it fails to request the same
region.

Maybe your 4.10 kernel didn't have CONFIG_WDAT_WDT (this appeared in
4.9).
I'm afraid, that is as far as I can help, you'd have to ask someone that
is more knowledgeable about x86 to go further (I've added the wdat_wdt
driver author in Cc).

So, I think I've confirmed your suspicion.  I booted Linux Mint with a 
4.10 kernel, and I see that the RTC took 0x70, and I don't see any 
watchdog listed at all.
