<br>
Thank you for your reply.<br>
<br>
I reflashed (same build) the BMC module with a hotplug. Now it works<br>
like a charm, it got an ip, I can log through ssh, reboot, etc..<br>
<br>
But now I have a new problem. If I try to boot from a halted system,<br>
with BMC module attached, the system fires up but Coreboot hangs:<br>
<br>
Unable to detect valid memory on any nodes. Halting!<br>
mct_d: fatalexit<br>
<br>
If I remove the BMC module the system boots fine.<br>
<br>
I have 4 Micron MT18JSF25672PDZ-1G4F1DD modules, located in CPU1 orange<br>
slots.<br>
<br>
I attach both console logs.<br>
<br>
Regards,<br>
