Hi James,

Yes. You assume correctly.

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?

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