Hi, has someone not only installed SUSE 9,3 on a Tyan S4882 but also succesfully booted after installation? Tyan S4882 with 8GB RAM, 4 x Opteron 848 and a 3ware 9500-12 SATA Controller works fine during installation. After the first reboot I got a Kernel Panic.

I can't see anymore output. I can install and! use FedoraCore 3 with all 4 CPUs and 8GB RAM. Thanks, Michael
