In a fresh install of 15.10 server, kernel 4.2.0-16-generic, I'm seeing the following entries in my kern.log file:
Feb 1 11:49:30 Client-5 kernel: [ 117.847487] MCE 0x1182: reserved kernel page still referenced by 1 users
Feb 1 11:49:30 Client-5 kernel: [ 117.847501] MCE 0x1182: recovery action for reserved kernel page: Failed
What does this mean? Is it important? How can one find more information?
