I'm not sure where to look to debug this problem.
I've been testing Suse 8. We have been on Suse 7 for about a year.
When I install Suse 8, it connects to VM's TCP/IP machine and runs just
fine. This is z/VM 4.2 btw. However, when I cycle Linux, it doesn't
connect back to IP.
But, if I cycle TCPIP when Linux is up, it connects ok.
If I cycle TCPIP when Linux is down, when I boot Linux, it connects ok
(first time only)
I'm using VCTCA connections.
As I've hinted at, I have not had this type of problem with Suse 7.

Not having reliable connections after booting is really getting to be a
pain.
