intelxl with loopback stuck during loading of ipxe.efidrv

[NiKiZe]

by building the pcii-d.x you would have a ipxe with only that driver supported see https://ipxe.org/appnote/buildtargets
Do you see the same issue with loopback when building and starting as a normal .efi?
Loopback should be part of normal dev testing: https://ipxe.org/dev/driver so seems odd that you have that issue.

On that note, I would recommend sending this to the mailing list - you might want to have a little less details in the mail, and refer to this thread.
