I am attaching the relevant part of the successful boot log from 2.6.12-rc2. I don't have a 2.6.11 boot log handy. I can boot it when I get home if it will help. I don't know if it is worth mentioning or not, but I have had to compile in the SCSI drivers since 2.6.12-rc1. Don't know if it's related to this or not.

One other note: I spent enough time tracing this to find that the message "target1:0:0: Beginning Domain Validation" seems to be generated by code that is in aic79xx_osm. Is this common code or should this code not be getting executed for aic7899 cards?

Actually, the code is in the scsi_transport_spi class. aic79xx still
has its own internal domain validation.

I'll be happy to try this when I get home.

Thanks ... it may not work; I don't have access to any drives with the
problem yours exhibits.

Yes, that's what I suspected. Here the internal aic7xxx DV has silently
configured the drive to be narrow. Probably because of cable damage or
something else.

Sorry I missed this before. The reason it is doing this is because this drive is connected using an adapter that converts an LC/LV (is this correct, off the top of my head) interface into a standard SCSI (narrow) interface. Could this be HELPING me here? :)
