Okay, I got video working on vanilla 2.6.16 by using "vbetool post" and
"vbetool vbestate restore" directly after "echo mem >/sys/power/state".

I copy all stuff need into tmpfs to ensure that it can restore the video
without hard disk access.

when accessing hard disks first time after resume, I get (wrote it by
hand so maybe this is not 100% correct)

ata1: handling error / timeout
ata1: port reset  p_ is 400000 is 0 pis 400000 cmd 8007
                          tf 80 ss 113 se 405000
ata1: status = 0x50 {DriveReady SeekComplete}
sda: current: senseKey 0x0 ASC  0x0 ASCQ 0x0

Sometimes there is "cmd 6" instead of "cmd 8007".

What to do, what to test?

I don't have any way of getting information out of my machine after
resume except on display (hard disks do not work after resume, the
notebook does not have a serial port and network does not work after
resume either) and by flashing keyboard LEDs, so transcribing huge dmesg
output would be a pain...

Please CC me since I am not on the list(s). Thank you.

OOhh.. clever, wish I'd thought of that,
as all of my (now solved) suspend/resume issues
were *all* libata related.

Randy Dunlop's libata-acpi patch might work for you.

One should not forget to disable swap first :)

So I guess it is a good idea to get SATA working first, isn't it?

I tried the 2.6.16-rc4 patches on 2.6.16 (one hunk did not apply in
libata.h, but I think I was able to fix it manually). Before suspend it
works well, after suspend it does not work. Seems that the timeout is
longer with the patch, though. I tried it several times; once it seemed
to have worked, but it was not reproducible (and it did not work any
longer after the next suspend), so I guess it could be just that I only
tried files already in cache. (Or alternatively, the patch has a success
rate of maybe 5%...)

"Just for fun" i tried the 2.6.15 patches on 2.6.15, but it did not even
boot.

BTW: It is an Intel AHCI controller.

Any other ideas/patches?

have you ever tried the sata_pm patch from http://tpctl.sourceforge.net/tmp/sata_pm.2.6.15-rc6.patch ?
i have a intel SATA ICH6M interface and it works fine with this patch.

bye...masc.

Tried it against vanilla 2.6.15 - no change.
