The patch was confirmed to work.

| That one worked despite the CTR error:

I'm not sure what's done during this 0.5 second period after CTR read
failure. At least only shuffling the driver init order for built-in
drivers didn't suffice.
A full log was requested, but I don't think it'll give much more
information.
