[Michele Berlingerio <1101883@xxxxxxxxxxxxxxxxxx>]

Update: it's random. Sometimes I get the errors, sometimes it connects it but without mounting it, sometimes it would mount it automatically.
I can't isolate the issue, but it seems to be still kernel related.

Btw, I had found at some point a patch for the kernel to make it
working, I had applied it, compiled the kernel and it was successfully
mounting the sd in 1 second. I can't find the patch anymore.

cheers
