[Firmware Bug]: CPU1: APIC id mismatch. Firmware: 1 APIC: 13

I see this error in the logs, is it something to worry about?
Think this is the issue:

Nothing to worry about.

I’m not sure why this issue came back. It was gone (I’ve commented on the firecracker GH issue). Perhaps since we upgraded the kernels in guest VMs.

We’re doing some changes that might “fix” this. If not, I’ll reopen the firecracker issue with more details.
