Do you have all 3 of the 2.2 IUCV patches applied? MTU size has nothing to do with connection errors (CTC or IUCV). The timeout error is what VM TCP/IP displays when the other side doesn't respond to an IUCV connect within 20 (?) seconds or so, indicating that the Linux side isn't quite right. You didn't post of VM TCP/IP IUCV configuration nor the options used on the netiucv module. You can #CP TRACE IUCV RUN CMD D G0 and #CP TRACE EXT 4000 on Linux if you want to watch what is going on.
