Booting Grub witch SPINWAI ERROR: AFECAL for cor 2 failurd

[RTOadmin]

Hi,
I have Fog Server with 86 iMac Intel for image distribution. It worked for two years. No I have one Machine that shows the error

“wlc_phy_radio2069_afecal: SPINWALIT EROOR: AFECAL for core 2 failed”
and the same for “core 1”

I booted with several USB Grub Bootsticks and got the same message every time.

The machine worked in former times with the same configuration.

Can you give me a hint?
Thank you
Mathew

This error does not seem to be very common. The only relevant information I find on the web is this log file: https://www.tonymacx86.com/attachments/2019-04-05_00-07-04-979981-airportbrcm4360_logs-001-txt.397495/

This does not look like a Linux kernel error message but something generated by macOS itself. Can you please take a picture or video of the error message on screen so we get an idea of the context?

Hi Sebastian,

thank you.

You are right it might be a Mac-Problem. After resetting the Parameter RAM ist works like before.
Many thanks
Mathew
