scsi on ultra 1 problem

i have a sun ultra1/170E where i want install Linux and all the Kernel
that i boot
cause problem with scsi

i test with 2.2.14-5 (from redhat 6.2), 2.2.17 custom (compiled with
Linux on Ultra5), 2.4-pre11 custom (compiled with the same Ultra5)

scsi controller seems be NCR53C9XF aka espfast
my hard drive was Quantum ATLAS II

and all my kernel say (this log is from 2.2.17):
