Okay, thanks for providing that Ian. I'm trying to think through what
might cause this case and how we might better handle this. I'm reviewing
the PRM but will probably need some time on this one.
One question I have is on this particular box are those on-board ports
shared with the BMC? And are you using the dedicated BMC ports? I'm just
wondering if, like the issue Dale mentioned with the X550, because we
have a shared management port, the link was up and we never really reset
it properly in the driver to run at full speed vs. it having been
programmed for other, more limited speeds by the BMC.
No, the BMC has it's own port.
Aha, the X540 has LPLU (Low Power Link Up) mode. So, I bet that we have
this in use on your X540 that's onboard, but not on the PCIe card.
Ian, if I have some time over the next week I can put together a custom
platform to test and verify that this is the case and with a potential
fix. Are these machines in a place where using a test platform would be
acceptable?
Yes, they are warming my office!
Cheers,

Ian.
