Enabling SMI workaround didn't make any change. What should I look after =
in boot logs?

Kernel parameter idle=3Dpoll displayed thermal warnings and freq. throttl=
ing after cca 30 sec. of application run.
But when fan speed was selected to Full speed at BIOS, the machine worked=
 fast as it should be. Quite impressive ;-)
Other idle options were same as none, only idle=3Dmwait frezzes during ea=
rly boot stage.

Thank you for your help.
