I just updated the AHCI PCI MSI support patch to support the latest
->host_stop() semantics changes that just made it into upstream.
This patch, until its merged, may always be found in the 'ahci-msi'
branch of
rsync://rsync.kernel.org/pub/scm/linux/kernel/git/jgarzik/libata-dev.git

Tested on an ich6 based system, with this ahci controller:
centera:~ # lspci -s 0000:00:1f.2 -v
0000:00:1f.2 IDE interface: Intel Corp. I/O Controller Hub SATA cc=raid
(rev 03) (prog-if 8f [Master SecP SecO PriP PriO])

And system boots and works fine, MSI isn't enabled of course.
Also tested on an ich7 based system (945G express chipset), with this

System boots and works fine (typing this message here), MSI is enabled.
I double checked with an added printk :-)
So that's at least one ACK for you. Now running NCQ and MSI enabled
ahci, I'm not sure SATA gets any better!

Any chance you could post a full /proc/interrupts output for this box?
