ML350 onboard NIC not seen in BIOS or OS after installing Intel X520 nic

Not sure if this is the correct category.

I have two identical ML350 Gen 9 (835847-035) servers running Ubuntu.  These were purchased in August.

The onbard NIC has been working fine with all 4 interfaces seen in the BIOS and by Ubuntu.

Today I installed a Intel X520-DA2 NIC on one of the servers. From Ubuntu the Intel card was shown in ifconfig but the onbard NIC was gone.  The activity lights on the NIC were dead.

I checked in the BIOS and the onboard NIC was enabled but the description in the PCI Device Enable/Disable BIOS menu now just showed 'Embedded NIC'.  On the identical other machine it shows 'Embedded LOM 1 : HP Ethernet 1GB 4-port  331i Adapter  - NIC'.

I've tried enabling, disabling the onboard NIC, rebooting etc but the onboard/embedded NIC will not return.

Any ideas?

A shut down and a 5 minute wait with the power out seems to have woken up the onboard NIC.
