If you want a slower computer, you might as well get a Mac.
It looks like its an interaction between disk encryption (usually a good idea) and the PCI-e control section within the microprocessor which is causing the delay.
Considering how much work put into getting PCI-e working on M.2 memory cards, this sucks.
Waiting for more info to come out
My older toshiba laptop seems ok after the fix.
[[But Walton found storage read/write performance to be an issue,]]

It was suggested somewhere that this patch will greatly slow down video editing. You don’t need no dang benchmark program to test that. And yet I have not seen a test done to date to show how much video editing is slowed down. If something took 20 minutes to render before then how long does it take now with the patch installed?
I run Linux Mint 18.2 on AMD quad core 8 meg hardware. I use the built in Radeon R7 graphics. Most processes do not appear to be impacted. HOWEVER, Civ V is no longer playable due to the slow response.
