Title: It looks like you have 1 guarded cores
Post by: dmoreno on March 12, 2025, 01:22:49 pm

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

Code: [Select]

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:  | |   | It looks like |
mar 12 19:53:48 kernel:  |_|   |  you have   1 |
mar 12 19:53:48 kernel:   _    | guarded cores |
mar 12 19:53:48 kernel:  (_)   \_______________/
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!

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.
