New Linux Kernel – No More “Meltdown-Slowdown” . .

Informative post by Greg Kroah-Hartman concerning substantial speed increases in the latest Linux kernel.   This matters because it mitigates the recent negative affects of the Meltdown patches.

For the clubs Mint & Ubuntu users . . . these systems will have normalized speed WITHOUT requiring additional patches OR risky micro-code firmware updates (yes!!).

Ubuntu 18.04 LTS, the recently named “Bionic Beaver“, will most likely be shipping with a Linux 4.15-based kernel. (per Michael Larabel at Phoronix . . Phoronix eBlog)

Warning . . re patches for Meltdown/Spectre . .

Lots and lots of online articles about the very negative consequences of just applying the fixes (patches) to all modern cpu’s of last two decades . .

As I relayed at the last meeting, in early January after applying one of the patches to a particular haswell based Intel cpu (System76 Sable AIO), the machine would not complete the startup boot sequence.   I had to reboot and select the prior running kernel (only happened twice in 18 years).   This is unacceptable for the average user.

For the millions of business, govt, edu, science and similar users, the problem is way worse.   All major cpu makers affected (Intel, AMD, ARM) for either Meltdown, Spectre or both.   (Spectre has several branches).

For those in doubt, here’s a post by the worlds foremost computer science engineer – Linus Torvalds:

Torvalds on Meltdown/Spectre Situation

How to Check if Your PC Is Protected Against Meltdown and Spectre (MS-Windows Only) . .

For all Windows users . . . in addition to the official MS patches, there are a second set of required actions to fix the Meltdown & Spectre security flaws.

Be careful as these updates are needed for the UEFI & BIOS firmware update & can brick your PC if done incorrectly!
