Čini se da je pronađen bug na Sky Lake i Kaby Lake CPU-ima. Potrebno je nadograditi microcode ili ugasiti HT u međuvremenu.
Auč!
One would expect that Microsoft will update its microcode driver in due course, at least for Windows 10. Less likely, however, is that the microcode drivers in Windows 7 and 8.1 receive the update. This is one of the implications of the company's new policy of only supporting Skylake and Kaby Lake in Windows 10; there's no need for Redmond to add Kaby Lake updates to Windows 7 and 8.1 when Windows 7 and 8.1 aren't supported on Kaby Lake chips anyway.
