NIC enumeration on BL20p G3 - sudden change

We are using the enhanced enclosures and the CGBE switches (the lower-end ones). We installed a large number of BL20p G3 servers. Given the way the OS numbers the NICs, physical port 1 is OS port 2, 2 is 3, etc.

We deployed our servers like this, and then, within a day or two after implementation, the NICs reassigned themselves so that 1 was 1, 2 was 2, 3 was 3, and 4 was 4! Needless to say this took every server offline. What could cause this? And is anyone else seeing this odd enumeration issues?
