<![CDATA[Strange "warning" in dmesg]]>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

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

Thanks!

BTW. If someone search for Qotom Bioses:

Disabling might cause more problems!

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

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
