Somebody in the thread at some point said:
| Most of time i have this error, but sometimes as this morning all
works fine!
| This morning i have boot the moko and it sees the SD:
| Rebooting the problem comes back again! Strange behavior!

Well normally at this point, negotiations are completed and you can use
the card without trouble.  All of the important aspects of the card
communication have been exercised.

I think these errors can be OK, it's the userspace trying to mount
things various ways, including the block device directly as FAT which is
seen on Windows formatted stuff sometimes.

Otherwise there are no real errors in this dmesg it seems.

Is it always changing whether it will show problems or not every boot?
So every second boot works?
