Panic when connecting USB drive to amd64

Excuse the crosspost, I don't know if this is amd64 specific or not.

I have a consistent panic when I connect a 2.5" LaCie 250 GB drive to  
a SuperMicro 6015P-TR. This server is running amd64 with ZFS and I  
want to investigate a way to use ZFS send/receive to external USB  
drives for backup.

Here is the panic message:

Please let me know if there is anything I can do to help debug this.  
This is not (yet) a production server, so I can try out various things  
if needed.

With kind regards,
