9.0 finds your SATA contoller like so:

ahci0: <ATI IXP600 AHCI SATA controller> port 
0x9000-0x9007,0x9008-0x900b,0x9010-0x9017,0x5018-0x501b,0x5020-0x502f mem 
0xd0409000-0xd04093ff irq 16 at device 18.0 on pci0
ahci0: AHCI v1.10 with 4 3Gbps ports, Port Multiplier not supported
ahcich0: <AHCI channel> at channel 0 on ahci0

9.1 gets stuck in some odd sort of loop where it thinks there a lot of 
channels:

ahci0: <ATI IXP600 AHCI SATA controller> port 
0x9000-0x9007,0x9008-0x900b,0x9010-0x9017,0x5018-0x501b,0x5020-0x502f mem

Hmm, in general it looks like it isn't able to read registers correctly.  I do 
not see anything wrong with the PCI bits in your verbose dmesg.  Can you do a 
binaray search to narrow down which commit breaks your machine?
