My GTR9 Pro seems to be just as stable on P110, I haven’t updated to NVM 1.40 as I’d rather wait for an official Beelink version.
The new firmware certainly addressed ACPI errors, I no longer get this AE_NOT_FOUND error during kernel init:
ACPI BIOS Error (bug): Could not resolve symbol [\_SB.PCI0.SBRG.EC0], AE_NOT_FOUND (20250404/dswload2-162)
ACPI Error: AE_NOT_FOUND, During name lookup/catalog (20250404/psobject-220)
