Panic screen

WD 2TB SATA disk in a USB dock.
The dock is detected as:

Jun  9 16:13:47 sandokan kernel: da0: <asmedia ASMT1153e 0> Fixed Direct Access SPC-4 SCSI device

Trying to rsync a directory tree to it, yields after a while a panic (see screen shots).
For the benefit of the search engine here is the transcript:
