Two problems. One is the command timeout which is failing- there are some
known issues I've been working on where interrupts are getting lost and things
time out.

The second issue here is the 'transport error'. That's the f/w blowing away a
command because of problems on the bus. Unfortunately there doesn't appear to
be any retry logic in the sd driver so this is getting back to the VM code
which is panicing.

I'm away for a couple of days, but I'll think about what I can change to make
this better.
