I tried it and guess what :)... swsusp doesn't work :@.

This time I was able to dump process states with sysrq-t:

My guess is ide2/2.0 dies (hpt370 driver), since last thing kernel prints is 
suspending device 2.0

Does it go away if you revert this?

No change.

That should only affect resume, not suspend, but it does mess around
with ide power management. Is this maybe happening on the *second*

Nope, the first one.

This looks suspicious. -mm does have several ide-fix-hpt3xx patches.

But hdc is not on the hpt3xx controller.
