The system was running in its UEFI mode (it also supports running in a Legacy BIOS mode). I was able to boot iPXE successfully from the 331i adapter but not from the 544+FLR-QSFP adapter -- the latter throwing the exception. However, I was able to boot to elilo 3.16 and SYSLINUX 6.03 (EFI) from the 544+FLR-QSFP adapter.

Did you check for a firmware update from Mellanox?

If the problem still occurs on the latest firmware, let me know and I'll 
loop in the relevant people at Mellanox.
