Linux boot issue.

Well... You can can likely fix this + the problem is some future update will create the same problem again.

Just create a small swap space + the problem will be fixed.

Hello,
Thanks for the reply.  By "small swap space" do you mean a partition?
I'll let you know how it works when I clarify your response.

I assume you use systemd for startup.

systemctl disable swap

probably stops that behaviour.

Swap space can also be a file  somewhere.  (as root)

dd if=/dev/zero of=/swapfile.keep bs=1M count=10   # 10 MB swapfile
chmod 600 /swapfile.keep 
mkswap /swapfile.keep

#and a line pointing to this file in fstab:
echo >>/etc/fstab   "/swapfile.keep      swap swap   sw 0 0"

Hello All,

I tried noci's suggestions with no results...  There was no swap enabled on my machine so I created a small swapfile and then rebooted.

I'm attaching the latest boot.log file, nothing appears to have changed...

"Unit file swap.service does not exist"

I saw this and it made me think...  could this be part of the issue?  I'm not sure what swap.service is and whether or not it should be there on my system???

cd /etc
grep -r -i swap\.service *

Let us know what you find.

No reason to reboot.

Just use the swapon + swapoff commands.

This will save your waiting for several minutes of boot time to ensure all's well.

Use this to see an overview of your current swap setup...

net14 # swapon --show
NAME      TYPE       SIZE USED PRIO
/dev/sdc4 partition 29.3G 780K   -2
/dev/sdd4 partition 29.3G   0B   -3
/dev/sdb4 partition 29.3G   0B   -4
/dev/sda4 partition 29.3G   0B   -5

For systemd  that most probably is:

cd /lib
grep -r -i swap\.service *....

anyway: systemctl list-unit-files should show the status of all services. Also the names, and also the failed services.

systemctl list-unit-files | grep enabled        shows all enabled units
systemctl list-unit-files | grep swap        shows all swap units
systemctl list-unit-files | grep enabled | grep -i swap        should show any enabled swap unit.

Use the name that shows up here to disable the service.

There is a manpage about cryptsetup.target which is less than helpful:
http://man7.org/linux/man-pages/man7/systemd.special.7.html

And the unit file is also less than helpful:

[Unit]
...
Description=Local Encrypted Volumes
Documentation=man:systemd.special(7)
...

So it is something handled Somwhere, Somehow in the systemd blob of code.....
The classic sysv scripting at least could be traced ...... ( the past isn't always better, but the future with systemd doesn't exactly seem to be nice as well).

I solved the issue and am still working to understand everything that was involved in its cause.  The main problem was in the /etc/initramfs-tools files. Specifically, one named 'resume'.

I edited out the reference to a non-existent swap partition UUID=1405da9d-f911-40b1-abea-fe2e33c52fd6 from the "resume" file in /etc/initramfs-tools. Ran 'update-initramfs -u' once again without errors.  This was a leftover reference to a deleted swap partition (there were two of them).  I remarked the second one out of fstab and then updated grub and initramfs.  Finally, no more lags in the boot process!

first run:
ken@BirdBrain:~$ sudo cat /var/log/boot.log
[sudo] password for ken:
Gave up waiting for suspend/resume device
/dev/sda3: clean, 2307125/19202048 files, 30419392/76799744 blocks

W: but no matching swap device is available.
ken@BirdBrain:~$

The other deleted swap partition was referenced in the fstab file: uuid-0d093982\x2d751[ **] (1 of 2)  After removing these two references and updating the relevant files all is well and my system boot time has decreased by a large amount.  The reason I edited the grub file was because I was trying to suspend the resume function during bootup but this was not the problem.  I finally discovered that the resume command for encrypting these deleted partitions was coming from the ramdisk via initramfs.  Once I got that figured out and removed the references everything was fine.

Many thanks to all who pitched in and tried to help.
