To issue of booting hang with APIC &ACPI, please verify http://bugzilla.kernel.org/attachment.cgi?id=1257&action=view
can help. Maybe we need to figure out what's wrong with the SMM & APIC timer.

Maybe we need to figure out what's wrong with the SMM & yl> APIC timer. Just checked this, compiled a 2.6.2 with ACPI 20040116 + the patch above. That patch rejects on arch/i386/kernel/apic.c because the ACPI patch (I believe) contains a half-fix for the issue, so the setup routine looks like ver = GET_APIC_VERSION(apic_read(APIC_LVR)); lvtt_value = APIC_LVT_TIMER_PERIODIC | LOCAL_TIMER_VECTOR; if (!APIC_INTEGRATED(ver)) lvtt_value |= SET_APIC_TIMER_BASE(APIC_TIMER_BASE_DIV); apic_write_around(APIC_LVTT, lvtt_value); the patch applies fine to drivers/acpi/bus.c, which is apparently missing in the ACPI 20040116 patch. When booting the machine with lapic enabled, the machine boots (!) and dmesg shows the "Found and enabled local APIC!" "Using local APIC timer interrupts." "calibrating APIC timer... [...]" messages. Of course, pressing Fn+F8 (switch CRT/LCD display) makes me hit http://bugzilla.kernel.org/show_bug.cgi?id=1963 http://bugzilla.kernel.org/show_bug.cgi?id=1890 and so the machine crashes hard & instantly, followed by reboot. Unless I want an "instant crash" key, I guess I better leave LAPIC off for now. .-) Regards, Georg -- Georg C. F.

In this case, as a workaround, APIC timer should be disabled
before any write operation to port 0xB2. Please refer
http://bugzilla.kernel.org/show_bug.cgi?id=1269#c18 .
I think it will help this case.

I don't understand your statement. How OEM could forget ot connect lapic ?
lapic is on the CPU.

That what I say with "MP processor do have lapic support", but in order to use it, you need external circuitry (IO-APIC, etc).

I think we need an alternative console which can be used to verify
whether the problem is lying in AGP.

Simple "modprobe intel-agp" will do, the system will reboot or hang when resuming from swsusp1/pmdisk even when AGP is not used.

Hmm, some of the Intel chipset code has resume callbacks already. These _will_ get called even if AGP isn't in use. I'm wondering if they're doing something they shouldn't. It might even be possible that those callbacks should just do nothing if agp isn't in use. Need to think some more on this one.

That's especially strange as Nigel's swsusp2 survives the suspend. Here's how it looks currently on my system [1]: pmdisk swsusp swsusp2 intel-agp not loaded OK OK OK intel-agp loaded, not in use (?) reboot OK intel-agp in use reboot reboot OK I haven't used pmdisk for some time, so I might be not authoritative.

Take a look at drivers/char/agp/intel-agp.c around line 1427 or so function agp_intel_resume(). Does it still hang if you just return 0 there ? I'm guessing that will fix it. Maybe we don't quite have the initialisation routine perfect, and reinitialising the chipset twice causes it to hang..

Did you have X running while doing that? I just ran a similar series with a Kernel 2.6.2 + ACPI 20040116 + the ACPI/LAPIC patch + swsusp2 on my machine [1]. LAPIC compiled in -- otherwise it won't link, see other mail -- but always booted with "nolapic" to disable "instant crash" button FN+F8. Results: agpgart intel-agp i830(DRI) X11 Result of suspend to disk and resume - - - without DRI OK * - - without DRI OK * * - without DRI OK * * * without DRI OK * * * with DRI hung upon resume So the mere presence of the AGP and DRM/DRI structures doesn't seem to create the conditions for things to fail. Only running an X Server that makes use of DRM/DRI does. But the intel-agp module is not without fault, either. Because when I load the i830 DRM/DRI, run the X server on it, turn X off, unload i830 DRM/DRI, the intel_agp still claims to be used by 1. Also, I tried S3 (suspend to ram) for the hell of it while running X11 without DRM/DRI but with agpgart module loaded. It showed the typical behaviour (suspends well, resumes very much successfully with many lines complaining about codec_semaphore (syslog attached), but very much functional (I can type on the keyboard to bring up the network and log in remotely). Unfortunately, the screen is entirely dead. I can toggle the /proc/acpi/asus/{brn,lcd} switches as much as I want without any change. (Un)loading agpgart doesn't change anything either. But when doing "modprobe intel-agp" now, the command just simply hangs. No reaction on that console... no output in dmesg, either. Trying a shutdown -r, the machine seems to be hanging somewhere, but since network is dead by then and the screen is dead, it is hard to tell where. Having the intel-agp module already loaded while trying S3 doesn't change the behaviour. Hope this helps someone to get a clearer idea what might be broken or missing, Regards, Georg [1] ASUS M2N Intel 855GM Centrio, more details at http://bugzilla.kernel.org/show_bug.cgi?id=1774 [-- Attachment #1.2: Type: text/plain, Size: 14334 bytes --] Feb 11 15:31:33 myhost kernel: Back to C!

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?

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.

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? Regards, Georg -- Georg C. F.
