[ipxe-devel] Problem chaining from ipxe to freebsd efi loader

[Raphael G]

Hello,

If this is not the correct place to report such troubles, sorry and do 
not hesitate to redirect.

When chaining from the ipxe efi binary to freebsd efi loader, the boot 
freezes during the loader code execution. See enclosed screenshot

https://dl.plik.ovh/file/G1s3BMIe8iLE0lka/26F6MpbbocfALMMq/freebsd_ipxe_boot_freeze.png

Not sure yet whether this is an ipxe issue or a freebsd efi loader one 
(both freebsd 10 and 11).

When reversing to far commit 35c5379760aa1fea5e38f7a78b090f92bb7813ee, 
from Dec 2014, we do not entcounter the issue

(issue appeared for sure before last July, so root cause must lie 
somewhere in the commits between 
35c5379760aa1fea5e38f7a78b090f92bb7813ee and 
df85901768622b8aea94d39a28effdbf90f7d4f0)

Is this a known issue ? Any clue on what could be the root cause ?

Regards
