Ah hah! I found the other SCSI suspend patch:

Anybody (Joshua?) up for reconciling and testing the two?
I just now tried out *only* "the other SCSI suspend patch",
and by itself it hangs on resume. Laptop computer, blank screen,
no serial ports, no printk()s visible.
And there's one minor bug in that patch: it uses GFP_KERNEL to
alloc a buffer, but on resume it really should use GFP_ATOMIC instead,
since the swap device is the same drive we're trying to resume..
2) sd should call START STOP UNIT on resume
That's probably why it hangs when used as-is by itself.
I may do some further testing.
Anyone else out there playing with this yet?
