Because with hint.hwpstate_intel.0.disabled=3D"1" it looks like on any other system and = on the versions before 13.0 If the system is idle it can work up to several hours now, but on any significant CPU load it freezes just several minutes after. --=20 You are receiving this mail because: You are the assignee for the bug.=
