It does not look like a pure software issue from the debug trace.
Host issues initialisation commands to the media (8, 5, 55), each is retried 3 times. For all of them, command execution fails with
hardware error flag set (and those are cleaned in between).
I still tend to blame improper hardware initialisation, but I'll try
to look and see if there can be something else.
