g_vfs_done() ada2p1 error = 5

[Christoph Kukulies]

I have a GPT partitioned SSD here which was serving as a boot volume of my previously installed
FreeBSD 8.0 and now, as I have 12.1 installed and booting from that I have mounted this SD into 
my running system.

In my system log I’m seeing the following error message (and when I try to mount that partition, I’m getting an
INPUT/OUTPUT error also):

g_vfs_done():ada2p1[READ(offest=262144, length=8192)]error = 5

What does this error message mean? How do I get rid of it?
