On my Thinkpad x60s, with 2.6.26-r2, when I resume after sleeping, I can't unblank (sometimes, maybe 1/10 times). It worked perfectly with -r1. I'm investigating the matter further). More details at http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=504167 I guess worst case we can make a -r3 without the .6 patches.
Can you please do a bisection of git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-2.6-stable.git ? The individual 2.6.26.x releases are tagged, which you can use as bisection points. Ask in #gentoo-kernel if you need help. Thanks!
I did that in a plane.. The offending commit is 7f0a673a75d3f9f50a64f83055b71be67526efd7 clockevents: prevent multiple init/shutdown My guess is that it exposes another problem, that its not really broken Also see upstream bug http://bugzilla.kernel.org/show_bug.cgi?id=11978
Created attachment 172143 [details] revert the bad commit (and a dependency) OK, given the lack of response upstream, let's just revert the bad parts. Please apply this patch to 2.6.26-r2 and confirm that the problem goes away.
With this patch, it resumes like a charm!
Fixed in genpatches-2.6.26-4 / gentoo-sources-2.6.26-r3, thanks for feedback and testing
Arg, I'm still getting the resume problem with -r3 .... Maybe we should review the whole serie of clockevent patches ? I'll try and come back to you...
Arg, seems like I was a bit too quick here.. It also break with -r1, so its a different problem.. most likely with the newer intel X drivers...
jfyi: i experience (probably) the same problem on my x60s using 2.6.25 kernel series. i currently use gentoo-sources-2.6.25-r8 with 2.6.25.20 and reverted patch-2.6.25.17-18 because it breaks resuming on this box.

My X problem is a deadlock in the kernel's DRM code with a recent X/intel drivers. I haven't taken the time to investigate it yet.
Created attachment 174330 [details, diff] revert patch (introduced in 2.6.25.17-18) that breaks resume this works for me with gentoo-sources-2.6.25-r9 and 2.6.25.20.
