Ok, I can post the results, does it make the difference if I post results from the 'normal' distribution and not from yours (modified)? That's so weird, so previously it was working because no programmatic check was done by DSDT? I agree, new bios should be tried, but since it's a critical step and I have critical projects with upcoming deadlines and can't afford the risk... next time I'll use warranty I will ask for an update...
