Server Will not Boot - MCX755106AS-HEAT

I have multiple ConnectX-7 (OPN = MCX755106AS-HEAT) devices in a GEN4 PCI Express chassis. If I allocate one to a server the server fails to boot. It doesn’t matter which device is allocated, the result is the same.

I have updated the firmware on these devices to version 28.47.1088 (the previous version was 28.44.1036).

Has anyone experienced this kind of an issue? If so, how did you resolve it?

Thanks.
