Good evening; Abel thanks for your quick reply. The sym53c8xx modul isn't loadde at boottime. When loaded by hand via modprobe it takes suspiciously long time to come up - and finanally nothing has changed - everthing dead as the cemetry of Chicago. Only lspci gives a hint that there is something in the slot. I'll take your advice and play around a little bit with the driver parameters. See you later.
