I've upgraded my PC to snv_60, and then fitted an Adaptec 29160N card,
and attached a SCSI hard drive.
I have then followed frava's recipe and have duplicated the core dump quite
easily.
As I only have one PC with Solaris, the target and initiator both run on the
same PC, and go through the loopback adaptor. This now works without any
special tricks.
Ok, here is the log of the commands & output:

Well I'm out of time for tonight. I will try with truss tomorrow to see if it
gives any thing further.
Thanks
