Hello,

Thank you for your reply.

I reflashed (same build) the BMC module with a hotplug. Now it works
like a charm, it got an ip, I can log through ssh, reboot, etc..

But now I have a new problem. If I try to boot from a halted system,
with BMC module attached, the system fires up but Coreboot hangs:

Unable to detect valid memory on any nodes.  Halting!
mct_d: fatalexit

If I remove the BMC module the system boots fine.

I have 4 Micron MT18JSF25672PDZ-1G4F1DD modules, located in CPU1 orange
slots.

I attach both console logs.

Regards,

- Eli
