Randy,
I thought so but it's not picking "ide-scsi.debug=3" up:

The code uses Rusty's moduleparam.h and it worked
for me with scsi_debug. [It is some time since I checked
scsi_debug built-in.] Could you try "idescsi.debug=3"
(i.e. drop the hyphen). Failing that perhaps you could
build ide-scsi as a module.

It would be interesting to see what effect "suppress_reset=1"
has on this failure.
