How Intel Is Moving From Software Fixes to Hardware Redesigns to Combat Spectre and Meltdown
The problem that night for Singhal, who oversees the development of the architecture for all of Intel’s processors, was that something was wrong with the patches. Among all the millions and millions of computers in use around the world running Intel CPUs, one of the patches for Spectre was causing some computers to freeze up or spontaneously reboot. Though only affecting a tiny proportion of the market, the problems were widespread enough to spook PC makers and prompt a temporary recall of the updated software.
(And even stirred Linux creator Linus Torvalds to publicly proclaim Intel’s work was “pure garbage.”)
