I have a simple link task that checks the PHY for link, reads it. If

When board is reset, link is established and at the DHCP task this
code returns with NULL ?
dhcp = (struct dhcp

Honestly, from how you write it, that sounds like a threading issue. You
must not use that function (as many
others) from any other context than tcpip_thread!
Just to point out that this setup works for several years on several
devices and never had any problems
The fact that it works on 1.4.1 (what's 1.41?) does *NOT* mean anything.
The code could be wrong and just work by chance...
Maybe I haven't understood your setup correctly. In that case, please
try to describe it better :-)
