I'm not sure, that this g_vfs_done is related to the panic. I've attached
the drive to an uhci drived port on the same machine, started an fsck and
I've got an immediate panic:

trying to sleep while sleeping is prohibited

If I remember it correctly. The driver has some power saving feature
which shuts the drive down if it is not used for some time and spins it
up when a request arrives. But yesterday I powered the drive up... waited
some secunds and started then a fsck. So I guess it was not in a
"shutdown" state - So I wonder who requested a sleep ;)
