(remember to cc folks, or your post may go unnoticed)
I don't know, depends on what Jeff/James think of this approach. There
are many different way to solve this problem. I let the scsi bus called
suspend/resume for the devices on that bus, and let the scsi host
adapter perform any device dependent actions. The pci helpers are less
debatable.
Jeff/James? Here's a patch that applies to current git.
