Hi Sam,
The eth0 works with same kernel code and config on the motherboard without the NCSI on-off switch to connect the host pysical network card .
This new version motherboard only add the switch . Does this switch cause electrical signals time delay growth?
The ncsi eth0 has never connect successful on the new motherboard on OpenBmc while it works on AMI BMC. I guess there is something wrong with the driver.
Best,
xiuzhi

This likely means the Network Controller didn't respond to the NCSI
driver's probe process. If that happens even after a power cycle then
hopefully one of the BMC people can weigh in on how to make sure it's set
up correctly. If it only happens intermittently then it may be related to
the NCSI microcode.
Cheers,
Sam
