I think 2.6.25 is hanging on the probe of ide port1.
This is 2.6.24

and on one boot it did this: Probing IDE interface ide1...
I think it's going after ide1, even though it is not there. Not sure yet. Something is pretty wrong here, and it broke from 2.6.24 to 2.6.25.

Of course its looking for ide1, but as soon as it sees the missing bit in the PCI config space its going to give up.
I haven't been able to reproduce hangs with the legacy IDE driver running with v2 and 2.6.25 on norwich - everything is running fine:

pata_cs5536 is not healthy, however:
PCI: Unable to reserve I/O region #1:8@1f0 for device 0000:00:0f.2 pata_cs5536 0000:00:0f.2: failed to request/iomap BARs for port 0 (errno=-16) pata_cs5536 0000:00:0f.2: no available native port
Again, this is with v2, so your mileage will vary, but as far as the amd74xx driver is concerned, I don't think we're seeing a huge kernel regression. I'm going to take some swings at the pata_cs5536 driver and see if we can't make it better.

PS: In my config, at least, following the IDE setup is the USB setup - possibly you are hanging _there_ and just not seeing any intermediate kernel messages.
