These processor chips tend to be rather basic when it comes to rates and widths. The root cause, I think, is that the aic7xxx isn't starting out at async narrow for the first inquiry (because the original DV code I removed did this, and I didn't add an equivalent back). The latest aic7xxx patch should sort this out. So, to get all of these changes, could you start with vanilla linus kernel 2.6.12-rc4 (or tree based on this, but not -mm which already has some of the SCSI tree included) and then apply the SCSI patch at http://parisc-linux.org/~jejb/scsi_diffs/scsi-misc-2.6.diff and see if it works? Thanks, James
