There are a number of hardware errors logged. All on UM250 under Linux 5.10.70.
This one is spammed under load:
Code:

This doesn't look good. While I haven't encountered stability issues (and the log messages say "Corrected error"), I have trouble believing this won't cause uncorrectable errors or undetected errors at one point and corrupt my data.
Also, the BIOS seems to be full of bugs. I'm seeing these messages in the kernel log at boot:
Code:
ACPI BIOS Error (bug): Could not resolve symbol [\_SB.PCI0.SBRG.EC0], AE_NOT_FOUND (20200925/dswload2-162)
fbcon: Taking over console
ACPI Error: AE_NOT_FOUND, During name lookup/catalog (20200925/psobject-220)
ACPI: Skipping parse of AML opcode: Scope (0x0010)
ACPI BIOS Error (bug): Could not resolve symbol [\_SB.PCI0.GPP2.BCM5], AE_NOT_FOUND (20200925/dswload2-162)
ACPI Error: AE_NOT_FOUND, During name lookup/catalog (20200925/psobject-220)
ACPI: Skipping parse of AML opcode: Scope (0x0010)
ACPI BIOS Error (bug): Could not resolve symbol [\_SB.PCI0.SBRG.EC0], AE_NOT_FOUND (20200925/dswload2-162)
ACPI Error: AE_NOT_FOUND, During name lookup/catalog (20200925/psobject-220)
ACPI: Skipping parse of AML opcode: Scope (0x0010)
ACPI: 8 ACPI AML tables successfully acquired and loaded
And also:
Code:
tpm_crb MSFT0101:00: [Firmware Bug]: ACPI region does not cover the entire command/response buffer. [mem 0x9dc71000-0x9dc71fff flags 0x200] vs >
tpm_crb MSFT0101:00: can't request region for resource [mem 0x9dc71000-0x9dc71fff]
tpm_crb: probe of MSFT0101:00 failed with error -16
Although I liked the device at first, I'm now thinking of sending it back. Unless these problems are solvable. I just don't need a new system if it's potentially unstable.

Other bad things I've noticed only after buying:
  • Ethernet doesn't work very well (getting 100 MBit links)
  • SSD M.2 slot can't take NVMe SSDs (or can it?)
  • HDMI port can't do 4K 60 Hz, you get 30 Hz only at this resolution (at least it works on DisplayPort)
  • GPU is actually too slow to do high quality video playback at 4K 60 Hz (granted, maybe a mini PC simply can't do that much)
  • Apparently the PC can overheat (look at the other threads)
  • No good documentation, only the insufficient user manual and the forum (had to search quite a bit until I found out how to enter the BIOS boot menu)

1.Ethernet doesn't work very well (getting 100 MBit links)
Please install other systems to check, maybe this is a kernel driver problem. I suggest you install windows10 to check, if it also shows 100M network card under windows10 system, please let me know.
2.SSD M.2 slot can't take NVMe SSDs (or can it?)
The M.2 2280 slot of UM250 does not support NVMe protocol.
3.HDMI port can't do 4K 60 Hz, you get 30 Hz only at this resolution (at least it works on DisplayPort)
UM250 supports HDMI interface to display at 4K 60Hz. Please try using dual-channel memory.
4.GPU is actually too slow to do high quality video playback at 4K 60 Hz (granted, maybe a mini PC simply can't do that much)
Regarding this issue, due to the performance limitations of the CPU and GPU, if you need to play extremely high-quality videos, then UM250 is definitely not suitable.
5.Apparently the PC can overheat (look at the other threads)
Maybe you can provide me with temperature values or screenshots, and I will observe if it is normal.
6.No good documentation, only the insufficient user manual and the forum (had to search quite a bit until I found out how to enter the BIOS boot menu)
There are not many options that can be changed in the bios of UM250. We also do not recommend users to make changes at will. If you have any questions, please email Support@Minisforum.com.

No word about the logged hardware errors? Can you explain them? This is the most important issue, because it sounds like there's danger of reduced system stability.

See other thread.

Too bad, not necessarily a deal breaker, but annoying.
3.HDMI port can't do 4K 60 Hz, you get 30 Hz only at this resolution (at least it works on DisplayPort)
UM250 supports HDMI interface to display at 4K 60Hz. Please try using dual-channel memory.
It's possible that my display's HDMI port doesn't support 4K 60Hz, so I take this back and will take your word for it. I apologize.
4.GPU is actually too slow to do high quality video playback at 4K 60 Hz (granted, maybe a mini PC simply can't do that much)

Too bad.
5.Apparently the PC can overheat (look at the other threads)
Maybe you can provide me with temperature values or screenshots, and I will observe if it is normal.
I noticed that the system temperature as reported by "sensors" (the program that reads the hardware temperature values provided by the hardware) got quite high, I think it was at least 60°C. But I didn't write down the values and I didn't test this again, so it's possible that the temperature was much lower (or much higher) than that.
How long can the device run at full processing power, until it has to shut down?
6.No good documentation, only the insufficient user manual and the forum (had to search quite a bit until I found out how to enter the BIOS boot menu)
There are not many options that can be changed in the bios of UM250. We also do not recommend users to make changes at will. If you have any questions, please email Support@Minisforum.com.
It's up to me whether I want to change BIOS settings, and sometimes there are good reasons to do so. But my use case was not changing BIOS settings. I just wanted to boot from an USB drive (which contained a Linux system for testing) instead of the SSD. Other systems show a hint on the POST screen which key to press. In my opinion, you should change the firmware to do that, and extend your documentation.

As I said before, I suggest you install windows10 to check the Ethernet network card. Because it may be a problem with the linux kernel driver. Regardless of the result, please let me know, thank you.
5.Apparently the PC can overheat (look at the other threads)
The following is the overall temperature tested by UM250 using aida64 tool. for reference only.
1014
6.No good documentation, only the insufficient user manual and the forum (had to search quite a bit until I found out how to enter the BIOS boot menu)
Thank you for your feedback and suggestions

Running some torture tests (just letting a few parallel processes run for a few hours), I didn't run into any problems at least. One run with Linux 5.11 didn't show a single error, but 1 error after a reboot. Who knows what's going on. The system hovered around 69°C according to the temperature sensors. MAybe the hardware had a bad day when I used it for the first time?
