After completing the installation, complete with checks that the new hardware was working correctly, we modified our configuration file to reflect our new addition, and built a new kernel. During boot, the system successfully finds uba0 and all of the devices specified there, and announces that it has found uba1. unfortunately, as soon as it tries to access the devices on uba1 (via their probe routines), the system crashes. Another twist to this situation is that the generic kernel boots successfully, finds both uba0 and uba1, and even autoconfigures devices found on the second uba. We found that if we did not specify the csr and vector addresses for devices on uba1, we could not even successfully build the new kernel. Needless to say, we are somewhat confounded by this situation, and need to bring the system up ASAP. I scanned the archives of unix-wizards from the last couple of years, and the only entries which I could find with regards to a second UBA concerned special kernel mods necessary to make it work on 750's. If someone has seen problems similar to ours, could you please let me know how you resolved it? please respond directly to me, as the machine which is down is our exploder for unix-wizards. I will also summarize to the mailing list after we have determined what is going on. Joe Sventekucbvax!sventek%ucbernie P.S. Sorry that I cannot give you the exact error message when the kernel crashes, but I am sending this from home, with the console listings still sitting on the decwriter.
