Cyclic lag on Ubuntu 20.04 Intel® Celeron(R) CPU N3350

If you run:

dmesg | tail

After it ha happens, does it give clues?

dmesg | tail

uname -a
Linux HP-14-bs1 5.4.0-31-generic #35-Ubuntu SMP Thu May 7 20:20:34 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

Today I got my kernel updated but I noticed the system started ok, but the behaviour came back a couple of seconds.

I installed Ununtu 20.04 to another sistem before; a Dell Inspiron 11-3168 2 in 1 laptop and the computer behaved the same way. After installing another distro (openSUSE Leap 15.1) the machine works ok. That ruled out a hardware issue.

This question was expired because it remained in the 'Open' state without activity for the last 15 days.

The issue is already solved, after two possible scenarios:
a. newer kernel version update or
b. reclaimed disk partitions after standard install did no delete these.
Selecting LVM option did show the partitions left from previous OS and
allowed to be erased.

Now the OS is working normally.

This question was expired because it remained in the 'Open' state without activity for the last 15 days.

I managed to solve this problem, no more issues found. Thanks

What was the fix please? It may help others

If the problem has been resolved, then please visit https://answers.launchpad.net/ubuntu/+question/690774 and mark the question as "solved" by pressing the related button.

The issue was solved, after two possible scenarios:

a. newer kernel version update or

b. reclaimed disk partitions after standard install did no delete these.

Selecting LVM option did show the partitions left from previous OS and
allowed to be erased during reinstallation.

No more actions of my part was taken to return the OS to report any more issues.
