need pci=nomsi or ahci fails to resume

["Brian J. Murrell" <brian@interlinx.bc.ca>]

Hi,

I've got an Acer Aspire 4350 here which I'm having some suspend/resume 
difficulties.  I'm using the Ubuntu 2.6.27-9-generic kernel (I've also
had the same problems with a 2.6.28-rc8 kernel.org kernel and it 
suspends just fine and mostly resumes fine with the exception that I 
don't seem to have a working disk after the resume.  In dmesg I see the 
following errors:

Through some poking around, I have come to discover that I need to boot 
the kernel with pci=nomsi in order to have the SATA disk work after a 
resume (I don't really need the option just to have it boot with this 
kernel though unlike previous 2.6.24 kernels).

This bug looks remarkably like http://bugzilla.kernel.org/show_bug.cgi?
id=11178 however I've checked the source for the kernel I'm using and it
has the patch from that bug in it already and I've even built a
2.6.28-rc8 kernel and I still have the same problem.

With the kernel booted with pci=nomsi, after a suspend/resume the SATA
disk works and this is what I get in my dmesg:
