Intel has released an "advisory" aimed at everyone to STOP the rollout of the patches/fixes for Meltdown and Spectre vulnerability because it was borking a lot (and I mean A LOT!) of machines.
We recommend that OEMs, cloud service providers, system manufacturers, software vendors and end users stop deployment of current versions, as they may introduce higher than expected reboots and other unpredictable system behavior.
This advisory was made a few days after Linus Torvalds "losing it" was made public (HERE). Fun reading.
What I'm trying to say is all fixes have been pulled because no one knows what damages it will cause when applied. Everyone will have to wait-and-see.
