Hi Rafael,

I've compared the log messages during a suspend/resume (STR) cycle for my
HP 2510p notebook. In general the changes look OK, but I noticed a few
things that I think may be worth looking into.

The analysis is based on v2.6.29-rc3-100-gf2257b7 with the following relevant
extra patches:
- PCI PM: Fix suspend error paths and testing facility breakage
- ricoh_mmc: Use suspend_late/resume_early

Below a *pseudo* diff between messages from .28-rc7 and .29-rc3-100. I've
concentrated on showing _what_ messages are shown, not _when_ they are shown.
Messages are shown in the order they appear with .29.

I've added some comments in the "diff" to indicate points of interest.

Summary of changes:
- Most config restores now happen during resume-early, but there are still
some displayed later, including some duplicates.
- There are a lot more "PME# disabled" messages, both during suspend (which
seems redundant?) and during resume. There are a few duplicates and it
happen for a few devices for which it is not done during normal boot.

Cheers,
FJP
