I downloaded the latest iso's of Red Hat for the s390, inserted the newest lcs, qdio and qeth OCO modules (the latest versions) into initrd.img and attempted to install the OS according to the README procedures. We booted from the CD at the hardware managment console and answered the questions about network device, domain name, gateway, etc. Unfortunately, we were met with the following string of messages: "SIOCSIFADDR: No Such Device eth0: unknown interface: No Such Device SIOCSIFNETMASK: No Such Device SIOCSIFBRDADDR: No Such Device eth0: unknown interface: No Such Device SIOCADDRT: No Such Device SIOCADDRT: No Such Device" Our machine has both an ATM and a OSA Express card, so we made multiple attempts to get either card to work in every configuration that we could think of, but every time we got the same results. I'm glad to see that the "unresolved symbol tasklet_hi_schedule" has been dealth with, but we still are stuck with a mainframe that we cannot communicate with. If anyone has any suggestions, they would be greatly appreciated. Michael Lambert
