I recently was handed a Sonic microSCSI unit, a SCSI to Ethernet
adapter. Simon Burge gave me some advice and I now have a new
kernel (cross compiled from Linux) with a new SCSI driver
(if_ssce.c).

I also found the correct cables. Powering up the unit brought
no reaction. Some checking around identified a tiny, surface
mounted fuse (a clue: it is labeled F1) hidden under the dc-dc
module. Soldering a wire accross it cured the problem and I
got a green PWR LED.

I could see yellow blinks on the RX LED so this looks good.

Booting the machine with a new kernel detected the device,
probably too well (see console log below). I then attempted
to bring up the interface and the machine locked up with
SCSI errors. Unplugging the SCSI cable caused a panic.

For a first attempt maybe it is not too bad...

Simon, will you look into this driver or is someone else
handling it (if any)?
