Interesting problem cropped up on my new ESXi 6 installation. When I boot the server, the startup appears to hang at dma_mapper_iommu loaded successfully. The server itself continues to boot and runs just fine, however I can't access the server via the direct console.

I've tried key combinations (Alt + F1 / F2 / F12). Rebooting produces the same result.

The problem started after I replaced my nic. I was using a Broadcom BCM5751 however I was having some troubles with it dropping from the network randomly. I threw in an Intel PRO/1000 Pt Dual Port and it didn't have any connectivity issues, however now I have this problem.

Any ideas?
