If your laptop is one APIC victim, I think until this problem isn't resolved, suspend/resume also doesn't work, is my guess.

My laptop definitely experiences the ACPI+APIC troubles, but I'm not sure whether that is what you refer to as "victim." :)
However: suspend/resume _almost_ work under 2.6.x -- the problem is the AGP code, it seems.
If I disable AGP, DRM/DRI and the intel framebuffer (which depends on intel AGP! vesa fb is activated and works, though), compile at least yenta_socket as a module, I can do suspend to disk (swsusp2) on kernel 2.6.2 and resume even while X11 is running.
The moment I enable AGP (no DRM/DRI, no intel fb), things break.
As for S1/S3, it seems that S1 is almost/more or less working, but I can only wake up the machine with the power button and that creates an event to shut down the machine. :-/ Oh yeah: and the keyboard is broken after resume from S1.
On S3, the machine comes back up -- apparently with working keyboard, although I can't be 100% sure -- and the screen is dead. After typing "ifup eth0" on the console I can log into it over the network, though. :)
On the swsusp2 list, someone made a survey and found out that noone has AGP working on 2.6.x for their Centrino notebooks. So the problem really seems to be with the graphics/AGP/ACPI support of the Intel 855GM/PM chipsets.
Is there any way people can help to make sure someone finds the time to look into this?
Regards,
Georg

If you have DRI & FB disabled, AGP isn't going to get used. It's just dead code. For this reason, I find it hard to believe its causing a problem.

So was I... but empirical evidence pointed towards it.
Maybe it was a false positive created by the PCMCIA (yenta) stuff, which seems flakey wrt to ACPI/suspend/resume, but that is unlikely.
I am fairly confident that AGP breaks powermanagement for most Centrino notebooks, in particular the 855GM ones.
Btw: Does anyone plan to pick this up anytime soon?

Georg

Near identical symptoms with SiS 648FX / 963 chipsets, and desktop P4. I doubt this is 855 specific. More like any recent ACPI BIOS + AGP 3 specific. -Huw

Hi list
I would like to know your opinion about my guess.
MP processor do have lapic support, but actually that one may be broken if the OEM do "forget" to connect it. Therefore, forcing it like Linux does hang your machine not matter what.
Note that this statement may be false for the Asus, though, and it's not easy to be sure what actually is broken (ACPI IRQ routing code, or hardware bug).

If there is anything I can provide to clear this, let me know.
Right now it appears to be a kernel issue, as my ASUS M2N occasionally booted with APIC&ACPI just fine -- but not the 2.6.x kernels with the exception of 2.6.2-rc2, I think.

Georg
