Hi I am a developer at the opsi opriject (https://opsi.org). We use grub for our UEFI netboot component. Recently we received complaints from our customers that some of their devices do not perform the UEFI Netboot completely. The machine starts to load our bootimage and then displays the message "Error: couldn't send network package". The affected devices are mostly HPs. I have an HP 250G7 with newest firmware on my desk and I can confirm this. 850G8 are also affected witht he newest firmware. I analyzed those devices with wireshark and the network connection dies after couple of seconds. Today I received a video of another customer where the said error message is displayed in the grub menu on a Microsoft Surface Go 2.
Is this a known issue? What can/should I do to provide more information on this issue? I am using grub 2.02 and 2.04 wit the same error message.
