I patched 3.12.34 to 3.12.35 and the attached now happens at boot.
Sorry I don't have better than a photo, cannot get past this.

The root FS is EXT2.  It's admittedly an old test machine that I'm using 
to build up a new configuration, so the  BIOS is a bit old, but it's at 
least dual core, not totally ancient.

Let me know if you need more diagnostic

Thanks
