Subject: Re: [RFC][PATCH][0/8] PM: Rework suspend-resume ordering to avoid problems with shared interrupts

I've given this series a try on my HP 2510p. I've seen no regressions
with suspend to RAM.
Below is a diff between suspend/resume dmesg from before (based on rc5)
and after (rc7 + series) the patch, with some comments.
Nothing looks really wrong, but there are some surprising changes.
Essentially JFYI though.
Cheers,
FJP
