I tried with 6.04-pre1 - it made no difference, the same issue as with
6.04-pre2
I had a look through the syslinux code, but I couldn't work out if
syslinux.efi is responsible for the 2nd DHCP Discover I see via tcpdump
(I can't pretend to understand the code, so I might not be looking in
the right place)
i.e. is it syslinux.efi that tries a DHCP transaction between
downloading syslinux.efi and downloading ldlinux.e64 - or is this done
by the host's EFI PXE firmware ?
Thanks
