Comment # 15 on bug 903560 from grant k

I've now removed & disabled as much hardware on the machine as I'm able, rm'ing
kern mods until

lsmod
 Module                  Size  Used by
 binfmt_misc            17468  1 
 sata_nv                31853  3 
 dm_mod                111107  30 

to no effect; shutdown still restarts.
