 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!
