Hi all,

this is a a report trying to help track down the issues with suspend
and resume on Centrino based notebooks. 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- <TAbort- <MAbort+ >SERR- <PERR-
Latency: 0
Region 0: Memory at <unassigned> (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:

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. Here are the syslog entries:

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:

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. For reference, here are the 2.6.3-rc1 dmesg bootup messages for
that machine, further details about that machine can be found at
