Whoops. May have been a bit too hasty there. I'm not sure why that
doesn't reset it, but we've now got the following (really rather odd)
serial output. Does anyone have any idea what might be triggering this?
Shell builtins work fine, but anything else seems to explode very
messily. Memory corruption of some description?

NULL pointer dereference in filp_open; whats that strange about it?
Use printks to debug this one, nothing mysterious.

I can't see any way that a null pointer could get to filp_open without 
something already being very wrong - the kernel worked fine before 
suspend. Unfortunately, that's the one occasion that we've got the 
machine (an HP nc4000) to resume. Since then, it simply freezes before 
hitting "Back to C" despite having had no kernel or configuration 
changes. The behaviour is very non-deterministic, which makes me wonder 
about something in the suspend or resume process damaging state.

Hmm, strange. You may want to test if length of sleep affects it...

So it does reach the kernel, right? I don't know if I remembered that call 
correctly, but "lcall $0xffff,$0" should call the real mode BIOS reset 
code...
Anyone else who can correct me here?

Perhaps the disk driver is going mad? Has anyone tried to boot a kernel 
without any disk drivers with a minimal root system on an initrd?

Stefan

For those who suffer from strange S3 resume problem such as resume hang,
could you please try this debug patch.
It uses machine_real_restart to switch to real mode, and soon jump to
the S3 wakeup address. So it simulates how BIOS resume a system from S3,
but completely bypasses BIOS. If the system lives after S3 with the
patch, at least we can know the suspend/resume code path is ok and it's
not a Linux driver issue.

Thanks,
Shaohua

This works on a HP Compaq nc4000 which previously never comes back
from resume (except for one time in which case the kernel oopsed in a
strange way, as posted by Matthew the other day).  I see a yellow
'Linu' on the screen, then I hear the hard drive spinning up, the
screen comes back and I see 'Restarting tasks... done' on the serial
console.  (this is with init=/bin/bash console=ttyS0)

I tried to resume immediately when the screen goes blank and got the
following results.  Out of 9 trials I got:

 - 4x: it would say "Restarting tasks..." but then oops and hang
   immediately.  See the oops below.
 - 4x: come back and give me a shell - but it hangs
 - 1x: come back, give me a shell and let me type; built-ins worked
   but commands produced the oops posted by Matthew a few days ago.

So far it has never come back when I don't resume immediately.

The new oops I got is:

root@(none):/# mount -t proc none /proc
root@(none):/# echo 3 > /proc/acpi/sleep

If you've looked at this bug you will know that myself at and atleast
one other person experience a reboot on resume at a specific line in
the wakeup code:
http://bugme.osdl.org/show_bug.cgi?id=3586

One note about the code in the bug, my code for detecting PM is
backwards, so ignore it, what I say in this email is still valid.

Specifically, if I get rid of the pushl;popl then the computer does
not reboot.  See the attached diff.  The question is 1) is this
pushl;popl the final nail in the coffin? 2) Does windows not clear the
flags completely, but instead sets them to some "special value"?

The reason for (1) is because as I understand it, when a certain
number of illegal operations (3 iirc) are issued at certain times
(real mode iirc) the machine automatically reboots.  That could be
what we are seeing here.

The reason for (2) is because if I remove the pushl;popl, boot into
windows suspend/resume, and immeditaly boot into linux then the
suspend/resume works.  I have screen blanking issues, but I can type
blindly and the commands all work just fine (I can startx for
example).

Also, what flags are being cleared?  What is their meaning?  Can you
or someone on this list point me to the approriate documentation?  I'd
love to look at it and try to understand my hardware better.

I would encourage others following this thread to try my patch and
the the trick of doing a suspend/resume in windows followed by a
reboot into linux where you try suspend/resume.

Thanks,
Jason

Can you do a lspci -vxxx

a) After a cold boot into linux
b) After a warm boot into linux from Windows

and see if there's any difference between the two?

You got this wrong. It is three illegal instructions but
*nested*. Like error, error in fault handler, error in doublefault
handler.

Try replacing flags manipulation with any stack manipulation to see
what is wrong.

Like perhaps processor docs?

Ah.  Yeah, this isn't an area I know much about :)  Thanks for the
correction. 

> Try replacing flags manipulation with any stack manipulation to see

Do you mean try something like this? Replace the push 0 with push
0x1234 ; push 0x1234 ; pop ; pop and try to figure out which line
causes the reboot?

> Like perhaps processor docs?

Sure thing, (a) is called lspci-coldboot.txt and the other is

Yep, try pushl $0, popl %eax; if that causes problems, something is
seriously wrong with stack, otherwise changing flags hurts.

pushl $0, popl %eax gets the reboot.  So it's changing the flags that
is bad?

What should we try next?

??? You wanted it to reboot? If not, something is wrong with
stack. Not sure whats next.

I don't want it to reboot, I guess I got confused.  As you say, maybe
something is wrong with the stack.  It's weird that something would be
wrong with the stack, because the other test to check the
suspend/resume code path works like a charm, the machine will do the
fake suspend/resume just fine.

So the bios must be messing up the stack right?  Is there a way to
examine or dump the stack so that we can compare the stack when
windows does the suspend/resume compared to when linux does it?

thanks,
Jason

Well, we set up stack few instructions before that. But we do it in
quite a complicated way; could you just put stack at 0x00:0x200 or
something like that? Also test if push alone is enough to kill it.

Could you send me the code you want me to test, I'd don't know enough
asm to move the stack.  I tried replacing the line with the comment
about the ASUS board private stack with a line like, "mov $0x200,
%sp", but I don't understand it.

As for check about the push alone causing the reboot, I removed the
pop, and it still reboots, but to me that doesn't say that it's the
push that does it.  It could be the next line.  I'll try to put in an
infinite loop.

Thanks,
Jason

I added a loop "jmp ." right after the pushl and the machine still
reboots.  So the pushl does cause the reboot.

Hopefully, you can show me how to move the stack and I will try that
as well.

Jason

mov 0x200, %sp was good idea, but try to zero %ss, too. (xor %eax,
%eax; mov %eax, %ss).

Ok, this is probably a long shot, but try:

setpci -s 00:00.0 67.b=11
setpci -s 00:00.0 68.b=4f
setpci -s 00:00.0 6d.b=47
setpci -s 00:00.0 9a.b=0a
setpci -s 00:00.0 9b.b=1d

after a cold boot, and then see if that changes the behaviour. My
suspicion is that Windows enables some northbridge features that affect
the behaviour of the system in suspend. Working out /what/ would be much
easier with datasheets, but ATI and VIA don't seem willing to provide
them (if anyone could provide me with northbridge PCI configuration
register specs for any non-Intel chipsets, that would be astonishingly
helpful)
