SOLVED: The 1.2 BIOS update posted below fixed the issue.

Hello, I just received the CW-NAS-AMD-FP7-20G board. I pushed it through a few tests to see if the CPU and RAM are working correctly, and after such tests were successfully passed, I attempted to install Debian on the brand new Kingston KC3000 NVMe drive. Unfortunately, nearly instantly after Debian tries to access the drive, it starts showing kernel messages about "Buffer I/O error" and "critical medium error", causing the system to no longer be able to detect the drive. What's worse is right after that happens, if I reboot into the BIOS and check the list of NVMe drives, it's... empty. Only after I power off the board completely and boot it back on is when the drive is visible again, but the problem repeats itself when I try to boot into Debian.

I tried updating the BIOS to version 1.1, restoring default settings, trying a known working SSD and using a different NVMe slot, but nothing changes.

Please tell me the board is not broken out of the box and there's a way to fix this... Thank you in advance.

Please try updating to this version first. If the issue still persists, we hope you can provide more system logs for us to analyze the cause.

This is most likely a hardware compatibility issue. If you have an NVMe drive from another brand or model, please try replacing it. You may also run a memtest to test your memory.
