This particular case I think is "SD card controller model tried
to do something wrong".

Various uses:
* guest legitimately did something we feel like telling the user
about (eg "Card force-erased by CMD42")
* guest did something dubious but with defined semantics
("Unknown CMD", trying to do something when the card is locked)
* guest did something legitimate but unimplemented
* underlying block layer read/write failed (and we are about
to throw away the error rather than reporting it anywhere else!)
These would all be worth tidying up some day when we have a
sensible logging infrastructure to tidy them up into.
