Hey, we're getting somewhere. It works, in that it stops the panic.
I get the "ed0: unloaded" message, and the machine doesn't panic, but
there are still some problems. It seems that device_delete_child
is failing (I forgot to print the return code, but it is not zero),
and reinserting the card results in "ed0 already exists, using
next available unit number", and then the dreaded "driver allocation
failed" (presumably the resources have not been freed).
Putting in a different kind of card ends up with two children, so
it seems that the only part of the delete actually happens.
