Hi, All
I do some tests about suspend/resume on my two boxes. One is HP
laptop and the other is Asus EEEPC901. The suspend/resume can't work
well. Even after core is selected as the test mode, it still can't work
well.(echo core> /sys/power/pm_test)

Then I do the same test by using the 2.6.28 kernel. And
suspend/resume can work well.

Of course I will try to use the git-bisect to identify the first bad
commit ASAP.

make sure you try this patch from Rafael first (it's not on lkml it
appears - Rafael, mind resending the patch to this thread?):

Subject: [PATCH] PCI PM: Restore standard config registers of all devices early
(was: Re: EeePC resume failure - timers)

Would that also fix

I should add that pm_tests freezer, devices and platform work, but
processors fails (I didn't test core since I suppose that when processors fails, core will fail as well).
