Hi Ian and all others here in the list I''ve updated now the BIOS. Now i can boot with acpi. And unbelievable... i don''t have any problem to boot Xen 3.0 (this one which is shipped with SUSE Linux 10.0). At the moment i can say: PROBLEM SOLVED! So we can summarize: the qla23xxx driver does not work without acpi, don''t ask me why. Thank you very much for all your help.
