backglass Posted May 31, 2012 Share Posted May 31, 2012 Hi! I'm trying to fix the ACPI from Fujitsu Siemens Amilo PI 2550. To do this, I took the table dsdt.dsl and SSDT[1-2-3-4].dsl on linux (is the system I use). I put all SSDT tables in the DSDT file (In the method first method of the dsdt). The iasl doesn't show any error, only shows optimizations. I put it in the kernel and then I compile the hex, and still freezing. When I don't move the mouse, it blocks . To do this, I think there must be some problem with the SSDT (stepsteep) Problem: Freezes constantly (eg music , WIFI) My computer features: Core 2 duo. I followed this guides: http://www.insanelym...howtopic=181631 http://www.insanelym...dpost&p=1681409 http://pat.erley.org...#The__PSD_Field Thank you very much in advance PD:I haven't applied any patch in DSDT. dmesg+lscpi+ssdt+lscpu+dsdt.tar.gz Link to comment Share on other sites More sharing options...

Nik7 Posted August 3, 2012 Share Posted August 3, 2012 Why do you think it's SpeedStep error? Do you have the same problem under Windows or Linux? Link to comment Share on other sites More sharing options...
HUSABER Posted August 3, 2012 Share Posted August 3, 2012 You need very good smbios.plist....not from IMac or MacPro. Get app called Mactracker.app and see very good for the same hardware And enable thermal profile inside IOPlatformPluginFamilt.kext/Contens/Plugins/SMCPlarformPlugin.kext Every thing i upload there: http://www.osx86.net/view/2805-speedstep_without_dsdt.html Link to comment Share on other sites More sharing options...
