Thanks for the pointer, but is there somewhere you can download the
bloody full original message with headers so I can generate a proper
reply?

Also, last night I noticed that ata_port_resume() ( which is called
both for runtime and system resume ) was explicitly calling into the
pm core to set the runtime status to active.  I thought that was the
problem so I disabled that code and made it work the other related
functions and just return success without resetting the link if it is
runtime suspended, but it seems that the runtime suspend state is
being cleared already by the time the system resume is called and I
haven't figured out where yet.
