write protected SD card - mmcsd driver - unable to unmount / shutdown
The card reader work fine, but it happened I have inserted a write -protected SD card (just forgot to unlock the card)
The problem is that the UFS filesystem on the SD is however mounted read-write (which is the error), and subsequently any write tentative result in an error, additionally it is not possibile to unmount the filesystem, and not even possible to perform a clean shutdown: the only solution is an hard power off.
Obviously this is not a GhostBSD bug, and eventually must be solved upstream,. I'm reporting this only to have the info at hand.
