: BTW, there have been very few suspend/resume problems attributable to 
: our ACPI or APM code.  Almost all are in individual device drivers 
: (especially video) or bus (PCI until it got config register save support 
: although type 2 device support is still incomplete I think).

Type 2 device support is handled by cbb, and is complete as far as I
can tell.

: that are difficult to track without a bus analyzer.

Yes.  I believe that I suspend correctly, but when I resume, the power
light comes back on and nothing else happens.  Placing a beep in the
first line of the resume path results in no beep happening, which
suggests suspend didn't suspend quite correctly.  This happens even
when all I have in my configured device list is ata. :-(  I'm somewhat
frustrated by this turn of events, as you can well imagine :-).
