Strange "warning" in dmesg

fireodo

Hello,

i have a lab machine with a Q7XXG4P03 (Qotom i guess) motherboard, Intel Celeron J3455 processor 4GB RAM 4 Intel NICs (I211) and a 32GB Transcend SSD.
Recently i saw that in the dmesg there is a warning:

WARNING: L1 data cache covers fewer APIC IDs than a core (0 < 1)

I searched in the net but I did not find any clarification/explanation what that "warning" wants to tell me.
Despite of that warning the machine works flawless with pfsense CE 2.7.2

If someone can shed some enlightenment he/she is very welcome!

Thanks, happy New Year and all the best,
fireodo

Probably a bad APIC table. Update the BIOS if you can.

Thanks a lot, Steve! As I found out (in the mean time) there is no newer Bios for that mobo ... I have to live with it until a newer Bios gets released.

BTW. If someone search for Qotom Bioses:

QOTOM BIOS

You can probably disable it but I doubt it's hurting anything. Disabling might cause more problems!

I agree - disabling apic is not so good ;-)

BTW. If someone search for Qotom Bioses:

Mail them directly, often they offer to clients new bioses that are not
shown in their "mainstream" offer.
