RE: Suspend2ram on Toshiba Tecra A3 OR problem with S3 on new 915PM chipset system appears to be with SATA/IDE

[Ron Rechenmacher]

Hi,

I'm wondering if I'm having the same problem.
I was using a Dell M60 w/ 2.6.10 and 2.6.11.7 with no problems.
The M60 has 855PM chipset with integrated (ICH4) ATA IDE and the disk
is a parallel IDE disk.

The M70 is 915PM based with integrated SATA controller which somehow
(experts know?) can work with the IDE driver, but slow, but with the
SATA driver + SCSI works better. Anyway, the disk is still a parallel
IDE disk, so I suppose there must be some serial <-> parallel magic 
going on.
Anywho, when I suspend, all seems well, but when I try to wake, the
disk doesn't come back and if I wait long enough, I get some:
     journal commit I/O error
and sometimes some other disk timeout errors.
Sometimes the video screen comes pack and the mouse works and I can type,
but, b/c the disk isn't working, I can't do anything. Sometimes the video
doesn't come back, but the caps lock still works.

I've tried 2.6.10, 2.6.11.7, and 2.6.12-rc2

So, which driver(s) should I look at?
Or is there a simple chant to /proc that can wake up the disk correctly?
Or am I not doing something correctly before/after I
   echo mem >/sys/power/state
Or is the 915PM and/or SATA acpi stuff just (too) new and I should help
get it working?

The system does successfully suspend to RAM and wake up under windows XP :(

Any ideas/suggestions/comments or work for me to do?

Thanks,
Ron

The SATA drivers have no power-management support (i wonder how this could
happen, since they are brand new, but this is another story...). Jens Axboe
is fixing them up right now, you should be able to find patches for them on
LKML.

This does affect suspend to disk as well as suspend to RAM. Also, since it
seems timing sensitive, it works on some machines sometimes.

In my case the video (integrated Intel 915GM graphic chipset) never 
resumes correctly. However, I've noticed very similar issues with the
disk. Sometimes the hdd led is always on after resume, sometimes not.
With the old SATA/IDE driver the disk seems to perform some operations
but at the end the system crashes totally and even the caps lock doesn't
work.

As an open-source developer I know from autopsy how much such e-mail are
frustrating to the developers. However it's impossible to me to prepare
a valuable bug report on bugzilla - at the moment I see no way to
reenable the LCD after resume (no acpi_sleep flag works on this system)
and the system crashes every time eliminating remote access to a
console.

Thanks,

Have you tried the various tools to post your video bios after resuming?
In my case, I needed to use both video_post and vbetool vbestate restore
to get a working configuration (and even then, it's not perfectly
reliable yet - I'm running XFree86 4.3, and have been told it's better
with Xorg. This is an i830, by the way.

Regards,

Nigel

Is SATA supposed to be handled by the _GTF and _GTM/_STM methods in the 
DSDT, or are those limited to PATA? Either way, we should probably get 
round to supporting them - I'm coming up against a lot of hardware which 
doesn't successfully resume IDE.

It's not possible to run external commands because after every resume
the system doesn't react on keyboard events at all.

Are you able to tell whether scripts run?

They don't. The system crashes during resume at a kernel level.

...the driver need to do its own housekeeping anyway (flush queues before
suspend etc) which was definitely _not_ done in the SATA drivers.
BTW: at least with suspend to disk, i have not seen a broken PATA driver for
quite some time.

The issue is that there doesn't seem to be any code to program the IDE
controller from scratch. This isn't an issue with suspend to disk,
because the BIOS has set it up correctly to begin with. This isn't
always the case with suspend to RAM.
