Thank you Michael,

To date, this error has only occurred within the end user environment, I have been unable to recreate it in my lab.  I'm looking for options to increase the value of our debugging with the end user.  The network card being used is a Dell branded Intel X710 4 port SFP daughter card pci identifier 8086:1572:1028:0000.

The message

!EFI_ERROR (Status)

is coming from the EDK2 FreePool() function:


There are only a few places in iPXE that use FreePool().  You can enable debug for all of them using:


Are you able to provide remote console access to an environment in which the problem can be reproduced?
