1. Do you have a problem with functionality of the system, or are you just complaining that there are several lines of information/warnings/errors in the system logs?

2. Do you have the latest BIOS version installed?

SunBear (sunbear-c22) said : #3

@m-hampl,
1. My system is operational. Having said this, I think these ACPI failures are adversely affecting my system, i.e. causing my system to have non-optimal performance, though I don't understand it. Hence I am seeking assistance from domain experts advice/instruction to resolve the matter. Pls do not regard this question post as a complain.

2. Yes.

Best Manfred Hampl (m-hampl) said : #4

Please provide some information about your system, e.g. the output of the commands

uname -a
lsb_release -crid
dmidecode | grep -e Date -e Vendor -e Version -e Product | head -n 4

If you google for these messages, you will see lots of hits telling that these messages do not any harm
e.g. http://lime-technology.com/forum/index.php?topic=23336.msg206011#msg206011
"the messages themselves usually indicate that ACPI has been disabled in the BIOS (or disabled with 'noacpi' in your syslinux.conf file),
or, ACPI is poorly implemented in the BIOS,
or, the BIOS is using ACPI features not yet implemented in the linux kernel.

Look first for a BIOS update for your MB, make sure you've not disabled ACPI in the BIOS, and other than that, ignore the messages if everything seems to be working."

@m-hampl
Thanks for explaining.
I have relooked my syslog - the section reflecting the ACPI failures (see below).
They seem to occur between systemd Started Network Time Synchronisation and Started Trigger resolvconf update for networkd DNS.

I Googleg Network Time Synchronization and came to this webpage https://help.ubuntu.com/lts/serverguide/NTP.html
I realised ntpd was not installed after running the command ntpdate -s ntp.ubuntu.com. I installed ntpd, and executed it.

I also googled “rigger resolvconf update for networkd DNS ubuntu 16.04” and learned about
/etc/network/interfaces. This file contains:
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

I rebooted my system but still found the error.
They now appear when systemd performs Started Create Volatile Files and Directories and Reached target System Time Synchronized. See below.

Based on the above, my report failures seem to be related to network time synchronization.
Do you agree?
Can you point me to the next step?

Manfred Hampl (m-hampl) said : #6

I still do not think that these messages indicate a significant problem.

Why do you think that the are related to network time synchronization?
The system log collects messages (informational, warning and error) from different sources. The NTP messages are coming from a different source (system) than the ACPI messages (kernel). I do not see any relationship between them, they are just by incident happening at the same time.

Your case seems to be identical to bug #1553690

SunBear (sunbear-c22) said : #7

Noted.

I assumed a relationship between my failures to NTP because I assumed that the activities listed in the syslog occurred sequentially. Based on your reply, I understand this is not the case. Reading about systemd, i understand it performs concurrent and parallel processes at boot. Hence, like what you said, the logging of the logs by kernal and systemd at the same time are coincidental.

Given my report failure are similar to bug #1553690, I have link this question post to that bug and will Wait For A Bug Fix.

Appreciate your guidance.

Thanks. :)

Thanks Manfred Hampl, that solved my question.
