Subject: [parisc-linux] Status SPIFI SCSI

Hallo Ryan,

here some comments on my non-successful work so far.

I did code reading and used debug instrumented code
to understand the structure behind the linux SCSI
handling.

Further I studied the NetBSD code. 

One major point: We do not get any interrupts.
For my analysis I only had a look on the first
steps of SCSI initialization, so this was the
INQUERY command.

The spifi command routine is called correctly,
but it has a wrong logical implementation. As I 
have seen on other (older) linux driver, the
xxx_command() has to block, after the command was
successful completed by interrupt. But the interrupt
never comes !! Even a "long" delay for simulating
blocking does not solve this problem.
