980 Pro

Since you've run live OS from usb, that excluded potential problems with Samsung drive - coincidentally I have 2Tb 980 Pro that gave me problems on Windows (hard freezes, not detected in bios until power is disconnected from PSU), and works perfectly fine in laptop and CachyOS.

I will never buy another Samsung product as long as I live their TVs are ad-ridden, and their OLED panels carry only a 1 year warranty.

If you past your log messages to AI, it is smart enough nowadays to analyze it … It means ESXi sent an NVMe read command to that Samsung 980 PRO and the device itself returned NVMe status 0x281, which Broadcom documents as “Unrecovered Read Error.” In the same Broadcom table, opcode 0x2 means Read.
