A300 DeskMini Boot Problems

I own a DeskMini A300 since 6 months and I have two severe problems:

1)
8 out of 10 boot procedures (after pressing the power button) the PC won't start up properly. The power button is enabled, the cooling fan is running but than nothing happens, the video output is also off. I have then to press the power button to force shutdown and restart again. Very nasty.
I already opened a ticket at customer support some time ago. They proposed me to clear CMOS, reflash BIOS and so on. Nothing changed.

2) I have a second partition with Linux Mint Cinnamon Desktop 19.3.
Since the latest update of Linux Kernel (5.7) Mint won't shutdown. Same situation like when the PC is not starting properly: video output is off, power button is still on and cooling fan is running. But nothing happens. This will go on forever. This happens EVERY time I shutdown Linux.

My configuration:

DeskMini A300
Bios 3.6
No SATA SSD (Disabled in Bios)
Intel NVMe M2.SSD 1000 GB
2 x 8 GB DDR4 3200 RAM
Windows 10 partition
Linux Minut Partition with Grub Boot Manager

I am really disappointed about this buggy hardware!

I have exactly the same problem as in your first paragraph. One to one. I do not know how to fix it.

Config:

DeskMini A300
Ryzen 3400G
Bios 3.6
No SATA SSD
Intel NVMe M2.SSD 250 GB
2 x 16 GB DDR4 3200 RAM
Windows 10

Well, I contacted the support again under the same ticket number. Telling them that their suggestions did not work at all and a lot of people in the ASRock Support forum do have the same problem. I also posted a link to the relevant posts here.
They did not even take a comment on this. Their suggestion was that I should send the COMPLETE PC to the ASRock customer center to "repair" it. If I would deliver a good trouble description they would "definitely fix it".
I cannot do without my PC for several weeks. Also I have doubts that they will fix the problem after all I read here in the last weeks.
Today, I ordered a used Ryzen 5 2400G processor at eBay. My expectation is that the problems will be gone with it. I will post my observations here, soon!

Dear m4758406,

Thank you for choosing ASRock.

Regarding your case, please help to verify the HX429S17IB2K2/16 with your DeskMini number3.
If possible, please also help to exchange the CPU to verify.

Thank you!
Yours truly,
ASRock TSD

Today I updated to the new BETA firmaware 3.60H and it looks like all the problems are gone! I booted nearly a dozen time without any hanging during boot process. Additionally I noticed that the boot process is MUCH faster than with the old bios. Let's keep fingers crossed that this firmware update was the solution.

YEP, I kept saying AGESA/modules had fix's for PCIe issues as well (as does 1.0.0.5 and 1.0.0.6 but unaware if directly impacting A300), this is just confirmation.

Also, boot speed, yep, I kept saying that and Support is like "no it doesnt" (to boot speed increase/other fix's and that they dont apply to Zen/Zen+ which as myself, others and now you have experienced, it does)... YES.... IT..... DOES....
