Find out what is wrong and patch kernel to fix it? Now you know you
need to look at pnpacpi code...

Yes, I have to look at pnpacpi code... but does the dsdt matters for
this problem?
Surely, it is a bios bug (as usually.....). I will look at pnpacpi code.
Does anyone has the same motherboard?

Not necessarily. IIRC, somebody (Rusty?) said that serial consoles have had
problems with suspend for a long time and just sometimes work "by accident".
ISTR that they do not really save and restore the line settings etc.

So it does not need to be the BIOS, it can also be a plain broken driver.

But using pnpacpi=no, I disable the acpi code.. the "normal" pnp code,
what does on suspend? Does it simply do nothing? In the dmesg I don't
see anything related to pnp device reinit.
I tried suspend to ram on this motherboard. A strange thing happens..
the system goes to suspend and then suddenly resumes. Why?
How I can check if it's enabled a wake up device? There are no related
settings on the bios, only wake on lan (disabled). I think I must
debug interrupts...
