IDE disks now share sata drivers (libata I think it may be called).

If this is a brand new install then I'm very surprised that it's causing 
problems.  On an upgrade I could see that some programs would have 
configurations pointing to old IDE devices but for a fresh install I would 
have hoped for better.

I also had a problem on my upgrade related to the IDE->SCSI change.  All of my 
disks are software RAID consisting of one SATA and one IDE disk.  My computer 
is in sad shape - my SATA interface fails most of the time - so my RAID is 
one-legged consisting of IDE only.  On upgrade my only consistently working 
disk (hda) changes to sda (or maybe sdb, haven't looked closely) so the RAID 
code gets very confused - it cannot find hda or the redundant (usually 
invisible and not up to date ) sda.   I haven't had time to sit and see how 
to resolve this so I continue to boot into 2.6.22 kernel which boots my 
broken RAID just fine  Might try to tackle this today ...

I'm thinking on future installs I'll use LVM mirroring instead of md 
devices ... that won't solve my current problem of course.
