Since about one and a half week, I have frequent, out of the blue, kernel panics. MacBook Pro just give black screen with grey text and restarts. This is the report.
How can I fix this? Already went to an Apple Premium Service Provider. They looked and the hardware seems fine. Maybe a kernel extensions of software issue?
MacBook
A superseded version of the following Apple Support document contained the excerpt below: OS X: When your computer spontaneously restarts or displays "Your computer restarted because of a problem." - Apple Support.
"Note: If you find the term "machine check" in the "Problem Details and System Configuration" field of this report, it may indicate a hardware-related issue."
That excerpt has been removed but it remains relevant. That Mac has a hardware problem. The KP report specifically implicated its file system.
Your EtreCheck report reveals the culprit:
disk0 - Samsung SSD 970 EVO 1TB 1.00 TB (Solid State - TRIM: Yes)
The Samsung "EVO" series SSDs do not enjoy a good reputation among Mac users. Replace it with one that does.
As I already mentioned, i took it to an AASP. They didn’t find any hardware problems.
i booted into safe mode today, issue still exits. I made a second user, issue still exits.
i Downloaded the 10.15.6 combo update and installed it over my current 10.15.6 system, issue still exists.
I’ve run the AHT, no issues with the hardware.
i also ran EtreCheck, no hardware issues there.
I’m now think of doing a macOS reinstall via recovery mode. This should leave my files, data and email etc in place but gives me a fresh clean 10.15.6. Is that a good idea?

Did you ask them why you are getting kernel panics and Machine Checks if you don't have a hardware problem?
A kernel panic is almost always caused by third-party kernel extensions and hardware problems. You don't have any third-party kernel extensions loaded.

They've replaced the logic board today and that seems to have fixed the issue. No kernel panics for the last 8 hours!
Here's the Etrecheck report:
A Machine Check usually implies a hardware fault. You'll need to take it to an Apple Store or Authorized repair center.
Have you applied the juts released supplemental update to macOS 10.15.6 yet? That update fixed a lot of crashes and freezes.
It may be worth posting that Etrecheck report here. Someone may notice something you may have missed.
Thx John. How can you be so sure that the Samsung EVO SSD is the culprit? The AHT and the tests the AASP did said no hardware issues...
The KP report you provided disagrees.
AHT is designed to test Apple hardware. Apple has no interest in and does not support aftermarket hardware modifications.
Thx. Back at the AASP now. They’r gonna clone my SSD to another and test it.
They concluded its the motherboard. We'll replace it. SSD seems fine, just as the macOS and software.
frequent kernel panics under 10.15.6
