Created attachment 16201 [details] dmesg When upgrade to the new 2.6.25 kernel, I can not run any OpenGL program after resume. Here is the error when run glxgear after resume. $ glxgears Failed to initialize TTM buffer manager. Falling back to classic. intelWaitIrq: drm_i915_irq_wait: -16 And I find this in my dmesg. [ 119.568138] [drm:i915_wait_irq] *ERROR* EBUSY -- rec: 256129 emitted: 256130 The resume works fine with 2.6.24, so this maybe a regression in i915 drm model.

Some extra information for this, xserver-1.4.0.90, mesa-7.0.3, intel video driver 2.3.0 work fine with kernel 2.6.25. So it should be some problem caused by the git xserver or mesa. With the git xserver and mesa, if you close X, and reload the i915 kernel model after resume, glxgears works again.
I can confirm having this problem on a stock hardy install which uses: mesa 7.0.3 xserver 1.4.0.90 intel: 2.2.1 @Jie Luo: Are you saying that you don't see the problem with the same setup as I have, except updated intel driver? And that the problem reappears when you update mesa and xserver to git?

I haven't managed to get 2.3.1 working properly on my g965 machine on ubuntu (the resolution isn't correct). But I will try to install Fedora 9 later on, when I have time, and see how things work out there. As far as I know, Fedora 9 ships a 2.6.25 kernel. (Note that I'm only interested in updated drm modules because the modules from kernel 2.6.24 cause a whole lot of VBLANK wakeups while running compiz)

Created attachment 16547 [details] reg dump after resume and reload i915 kernel module
From the regdump, it seems some register not restore properly during resume. This maybe the problem.
Some updates, OpenGL program will work once you reload the i915 kernel module after resume, and you do not need to reload it again. OpenGL program works correctly after that, even you do another suspend and resume.
