Here you go:

   The spinning char can seemingly be in any position when it crashes. It 
took 5 attempts that time to get to the beastie menu.

   I suspected BIOS, that's why I was going to get a new motherboard. I've 
always had problems getting gptzfsboot working on this hardware and there 
are no more BIOS updates now. That's why I have ufs root, as it only 
worked intermitantly.
   Then I wondered what the hell was going on in the loader that took >60s 
and seemingly touched every drive. I assumed it was FBSD that was tasting 
all the drives.
