Well, we know the Kernel covefs driver didn't clean up it's allocations and caused corruption on a page. The pool is corrupt to the point where we cannot check who owned the page prior to the corruption. It's no longer a valid page, thus writing over all information.
Covefs is a Windows Driver Development Kit Kernel driver, I haven't used the kit myself, I have been meaning to give it a try.
I suggest you remove the package that this driver comes with, or the entire kit, whichever option is the most feasible for your machine. You could try an update as it dates back to June 2014, if that doesn't stop the crashes then remove the software.
