I have been on google looking into this issue (which I did not have the time for at work earlier).
I found this error has been reported dating back to 2009. I also found that this is not isolated to the Ubuntu kernel as I found reports on Fedora as well. So the problem is across distributions and has existed for some time. I found that the majority of other users from the brief reading I did only experienced disconnected wifi. However in my case, this issue resulted in data loss due to the hard lock I experienced. Namely my Intellij configuration for different environments on more than one project and some unsaved work I was in the middle of. https://www.google.com/search?q=Microcode+SW+error+detected&client=ubuntu&channel=cs&aq=f&oq=Microcode+SW+error+detected&aqs=chrome.0.57.180558&sourceid=chrome&ie=UTF-8 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1169300 Title: Microcode SW error detected.
