 The eMMC in this machine no longer passes the self test.  From OFW.

 I was working on the graphics driver DMA code and saw filesystem
 corruption.  The kernel code could have caused the corruption which led to
 the failure.  It is possible it could have just been coincidence as well.
 Regardless this machine has non cleanly shutdown many times while
 debugging the graphics clock hardware hang and other various bugs.
