Intel admits patch for chip flaw is causing reboot problems

Security patches for Meltdown and Spectre are slowing older systems down Intel sets world record for indoor drones

Intel is quietly telling some of its big customers to "delay" installing a fix it issued that was intended to address a major security vulnerability that became public last week, the Wall Street Journal reported.

The glitch underlines the difficulty of Intel's challenge as it rushes to fix the unprecedented vulnerabilities, say industry commentators. The firmware updates and security patches are starting to flow but, for some processor and operating system combinations, it will take time. Users running HDD drives will see a lessened impact as the bottleneck from the slower drive is greater than the impact of the potential patches. To accelerate the security of the entire industry, we commit to publicly identify significant security vulnerabilities following rules of responsible disclosure and, further, we commit to working with the industry to share hardware innovations that will accelerate industry-level progress in dealing with side-channel attacks.

The updates are intended to address a security flaw that affects nearly every Intel processor produced since 1995.

"Given the scale of the issue, the patches by Microsoft, Apple, Google and others have been very successful", he told TechNewsWorld. AMD said yesterday the issue should be resolved shortly. Unfortunately there have been reports on some AMD Windows PCs 'bricking', especially with patches for older AMD processors (AMD Opteron, Athlon and AMD Turion X2 Ultra families). More simply, the design flaws are rooted within the processor's architecture where a design defect allows applications to cross memory boundaries into the protected memory of other applications.

"If this requires a revised firmware update from Intel, we will distribute that update through the normal channels". Those running Windows 10 systems on newer CPUs would see minimal impact, it said.

Performance in the 7th Generation Kaby Lake H processors is said to mirror the impact in performance seen in the 8th Generation processors.

If you have already downloaded the updates and are faced with a PC that doesn't boot, Microsoft also provides troubleshooting instructions for, and.

Microsoft and others in the industry were notified of the issue several months ago under a nondisclosure agreement, Terry Myerson, executive vice president of Microsoft's Windows and Devices group, noted earlier this week in an online post.
