To make it easier to find in the future, I also submitted it as http://bugzilla.kernel.org/attachment.cgi?id=2062&action=view for http://bugzilla.kernel.org/show_bug.cgi?id=1877 ------ All of this on ASUS M2N with kernel 2.6.3-rc1 + acpi-20040116-2.6.3 patch. When booting 2.6.3-rc1, I found an apparent inconsistency in the AGP code, as dmesg reports agpgart: Detected an Intel 855 Chipset. agpgart: Maximum main memory to use for agp memory: 431M agpgart: Detected 8060K stolen memory. agpgart: AGP aperture is 128M @ 0xf0000000 while the chipset is Intel 855GM; output of lspci -vvv 00:00.0 Host bridge: Intel Corp. 82852/855GM Host Bridge (rev 02) Subsystem: Asustek Computer, Inc.: Unknown device 1751 Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR+ FastB2B- Status: Cap+ 66Mhz- UDF- FastB2B+ ParErr- DEVSEL=fast >TAbort- SERR- (32-bit, prefetchable) Capabilities: [40] #09 [a105] Detection seems to be done in drivers/char/agp/intel-agp.c, in function agp_intel_probe, more specifically in the part case PCI_DEVICE_ID_INTEL_82855GM_HB: if (find_i830(PCI_DEVICE_ID_INTEL_82855GM_IG)) { bridge->driver = &intel_830_driver; name = "855"; } else { bridge->driver = &intel_845_driver; name = "855GM"; } break; I don't know enough about the PCI ID intrinsics to tell what is the difference between PCI_DEVICE_ID_INTEL_82855GM_HB and _IG. If nothing else, the reporting is misleading, as all information and documentation reports this laptop with "855GM" chipset, while the Linux kernel claims it is "855" (without "GM"). I'm not sure whether this is because a) the chipset should really have its own routines, but depending on some different implementations, the 830/845 driver can be used as a cludge. or b) the chipset comes in two different implementations and the i830/i845 drivers are what should be used. In any case: given that the logic is right, I propose to change the reporting to "855GM (i830)" and "855GM (845)" to avoid confusion and allow easier telling by dmesg messages which driver is used. *** Suspend to RAM When trying suspend to ram (S3), it showed the same results as 2.6.1: the machine seems to suspend find with "echo 3bios > /etc/acpi/sleep" and it seems the machine comes back -- only the screen is entirely dead. So I tried changing the agp_intel_resume function in intel-agp.c to static int agp_intel_resume(struct pci_dev *pdev) { struct agp_bridge_data *bridge = pci_get_drvdata(pdev); if (bridge->driver == &intel_generic_driver) intel_configure(); else if (bridge->driver == &intel_820_driver) intel_820_configure(); else if (bridge->driver == &intel_830_driver) intel_i830_configure(); else if (bridge->driver == &intel_840_driver) intel_840_configure(); else if (bridge->driver == &intel_845_driver) intel_845_configure(); else if (bridge->driver == &intel_850_driver) intel_850_configure(); else if (bridge->driver == &intel_860_driver) intel_860_configure(); else if (bridge->driver == &intel_830mp_driver) intel_830mp_configure(); else if (bridge->driver == &intel_7505_driver) intel_7505_configure(); return 0; } to try bringing back things to life. However, suspend to ram (S3) as above shows similar behaviour with the syslog reporting: Feb 8 14:51:26 myhost kernel: PM: Preparing system for suspend Feb 8 14:51:26 myhost kernel: Stopping tasks: ==========================================| Feb 8 14:51:26 myhost kernel: hdc: start_power_step(step: 0) Feb 8 14:51:26 myhost kernel: hdc: completing PM request, suspend Feb 8 14:51:26 myhost kernel: hda: start_power_step(step: 0) Feb 8 14:51:26 myhost kernel: hda: start_power_step(step: 1) Feb 8 14:51:26 myhost kernel: hda: complete_power_step(step: 1, stat: 50, err: 0) Feb 8 14:51:26 myhost kernel: hda: completing PM request, suspend Feb 8 14:51:26 myhost kernel: PM: Entering state.

Feb 8 14:51:31 myhost kernel: Bank 1: f200000000000175 As I wasn't sure whether the chipset detection was correct, I forced usage of the 845 driver by modifying the logic above to case PCI_DEVICE_ID_INTEL_82855GM_HB: bridge->driver = &intel_845_driver; name = "855GM"; break; The kernel boots up normally and everything seems to work just like it did for i830. Unfortunately, that includes suspend 2 ram (S3), which shows the same behaviour.

Feb 8 13:19:44 myhost kernel: Bank 1: f200000000000171 So regardless of whether it is (a) or (b) above, it seems that both i830 and 845 are unable of bringing the video chipset back to life on my Intel 855GM Centrino notebook. Given the posts of some people that suggested some success with the 830mp driver for some laptops, I also tried using that -- and it behaved precisely like the i830 chipset. Screen was dead after S3, but the syslog seems less catastrophic: Feb 8 15:22:03 myhost kernel: PM: Preparing system for suspend Feb 8 15:22:03 myhost kernel: Stopping tasks: ==========================================| Feb 8 15:22:03 myhost kernel: hdc: start_power_step(step: 0) Feb 8 15:22:03 myhost kernel: hdc: completing PM request, suspend Feb 8 15:22:03 myhost kernel: hda: start_power_step(step: 0) Feb 8 15:22:03 myhost kernel: hda: start_power_step(step: 1) Feb 8 15:22:03 myhost kernel: hda: complete_power_step(step: 1, stat: 50, err: 0) Feb 8 15:22:03 myhost kernel: hda: completing PM request, suspend Feb 8 15:22:03 myhost kernel: PM: Entering state.

Feb 8 15:22:06 myhost kernel: Bank 1: f200000000000175 So it seems that the "soft suspend" functions (S1, S3) simply don't work with Kernel 2.6.x and Centrino (Intel 855GM chipset) notebooks. *** Suspend to disk I wasn't able to get suspend to disk to work, either. The suspend to disk worked fine, but resume crashed at Waiting for DMAs to settle down... double fault, gdt at c03c0300 [255 bytes] double fault, tss at c0465800 eip = c0116f8b, esp = df4ebf80 eax = e0971884, ebx = e0971680, ecx = 0000007b, edx = 0000007b esi = 00000000, edi = c011617e and after a while the fan turned itself on to full blast. As software suspend V2 doesn't have a 2.6.3 patch yet (and the 2.6.2 patch creates rejects), I couldn't try it with 2.6.3. When trying it with 2.6.2 the suspend worked, but resume died (crash/reboot). *** Other suspicious stuff The lines MCE: The hardware reports a non fatal, correctable incident occurred on CPU 0. Bank 1: f200000000000171 which appeared in all syslogs above seem suspicions. Bank 1 sounds a lot like "memory bank" -- but that number sounds quite high. Hope this helps. Regards, Georg P.S. Oh, and enabling ACPI & Local APIC now crashes (instant reboot instead of freeze) the machine on boot. P.P.S.
