I wonder if this problem with HP EFI firmware affecting cur...

>>> Looks like the patch mostly addresses the initial search to find the right handle for PXE.? I think I found the remaining source of the issue (the part that's generating the handle->Configure() messages). I'm trying to read through pieces of the EFI spec, gnu-efi API, and a few other sources.? I'm pretty certain you'll see that the previous patch/binaries

Hi All, My PXE configurations works fine for a bios PXE (the server in legacy mode) but hangs in an EUFI mode. Look like it can transfer the bootx64.efi but not the next one ldlinux.e64 Any ideas?
