I was copying from an external USB disk to an NFS mount and under constant 30MB/s IO the disk dies reproducable:

Also, after resetting the system the loader hangs here when seeing the disk that was gone.

The system is a Sun X4470 running OpenIndiana hipster:

SunOS beast 5.11 illumos-bd05d33960 i86pc i386 i86pc

The disk is attached via USB2:
