It looks like you have 1 guarded cores

(1/1)

I own a Talos II running Linux 6.6.62.
Since a week ago, I'm getting the following message on the logs:

--- Code: ---mar 12 19:53:48 kernel:   _     _______________
mar 12 19:53:48 kernel:  | |   /               \
mar 12 19:53:48 kernel:  | |   |    WARNING!   |
mar 12 19:53:48 kernel:  | |   |               |

mar 12 19:53:48 kernel:   _    | guarded cores |
mar 12 19:53:48 kernel:  (_)   \_______________/

--- End code ---
I didn't get those before, and I haven't installed a new kernel for months.
Also, I can't find much information about it on Google, other than a couple of references to kernel's source code.

Can anyone shed some light on this?
Thanks!

ClassicHasClass:
Likely there was some glitch that caused one of your cores to get guarded out. You can clear this condition from the BMC: https://www.talospace.com/2020/05/the-case-of-disappearing-core.html

Thanks! I'll try that.
