Dell and HP Advise All Their Customers To Not Install Spectre BIOS Updates (bleepingcomputer.com)
An anonymous reader writes: The Spectre and Meltdown mess continues with Dell now recommending their customers to not install the BIOS updates that are supposed to resolve the Spectre (Variant 2) vulnerabilities. These updates have been causing numerous problems for users including performance issues, boot issues, reboot issues, and general system stability. Due to this, Dell EMC has updated its knowledgebase article with a statement advising customers to not install the BIOS update and to potentially rollback to the previous BIOS if their computers are exhibiting "unpredictable system behavior". ZDNet reports that HP too has issued a similar advisory. The computer manufacturer pulled its softpaqs BIOS updates with Intel's patches from its website, and said it would be releasing a BIOS update with a previous version of Intel's microcode on Thursday.
I have a Gigabyte motherboard and a Skylake Core i5 and installed the new BIOS update (which says "Update CPU Microcode") and so far it seems to be going good. No random reboots or crashes and no noticeable slowdowns.
