mptable output of the system is located at: http://www.lecad.uni-lj.si/~leon/other/x7sb4/mptable.txt I could not change version in BIOS. Processor option supported by BIOS are shown in http://www.lecad.uni-lj.si/~leon/other/x7sb4/img_1638.jpg I have added options INVARIANTS options INVARIANT_SUPPORT options DIAGNOSTIC and now GENERIC shows the following trace when ACPI disabled: http://www.lecad.uni-lj.si/~leon/other/x7sb4/img_1639.jpg http://www.lecad.uni-lj.si/~leon/other/x7sb4/img_1640.jpg http://www.lecad.uni-lj.si/~leon/other/x7sb4/img_1641.jpg Forcing single core in BIOS helps when running ACPI disabled. Toggling other BIOS options like C1 Enhanced Mode or Speed Step does not. Kind regards! Leon Kos, CAD lab, Mech.Eng., University of Ljubljana, Slovenia (http://www.lecad.uni-lj.si/~leon)
