Re: Boot error

Make sure to remove the quiet parameter, take pictures of the monitor (scroll up as much as possible to cover as much log as possible) and link (please don't embed huge pictures) them here.
emergency mode likely means you cannot mount the root partition nor any other filesystem and then preserving/posting journals will become tricky.

Re: Boot error

Check if your PC boots with split_lock_detect=off kernel parameter, but if it works, don't leave it as is 'cause it's a security breach. Investigate and find what's happening. Maybe it's an evil rootkit.
