See my analysis there:
I suspect it is related to the gethostbyname() bug.
Markus has judiciously noticed that all the problematic software use
reception of UDP packets.
Since this problem only affects mintv4e.prg, I have a big suspicion
about the UDP checksum routines. They are written in assembler, and they
were tricky to convert to ColdFire (lack of ROL/ROR instructions, etc.).
We should start by adding (or enabling) debug trace on the reception of
UDP packets, to see what's happening.
Also, since we experience huge timeouts, we should determine what the
kernel is doing during that time.
