Hi.

When I'm trying to suspend to mem one machine, it wakes immediatly back with
nothing notable in dmesg:
[--snip--]
Will PM_DEBUG or ACPI_DEBUG help somehow? Or later kernel?

Later kernel might help, some important fixes have gone in since 2.6.19,
PCI quirks-related etc.

Please try 2.6.20-rc7 and if that doesn't help, try the latest -mm.

2.6.20 from init 2 is no go either, -mm (-rc6-mm3) with minimal config [1]
suspends, no key was able to resume it back, only power button, but monitor
doesn't wake (actually I've this problem on another machine when X is not
running) -- how to debug both of this? Do not suspend consoles? PM_TRACE (this
won't help since it completely resumes, I guess)?

First, you can try s2ram if you haven't done it already (http://en.opensuse.org/s2ram).
It may help to get your video back after the resume.

If you have a COM port, it is also possible to use a serial console throughout the
suspend/resume cycle.

This is blindly written dmesg after resume. See it whole at [2]:

This looks like an ACPI-vs-IDE problem. You can try to use libata drivers instead
of the "old IDE" ones.

Do you want acpidump?

I'm not an ACPI expert, it won't tell me a lot, but perhaps you should add
linux-acpi to the Cc list. ;-)

Should I test 2.6.20 with minimal config?

I think it's better to try the -mm with the minimal config.

Greetings,
Rafael
