[ACPI-sppt] S3 debugging / Vaio

Hi,

I'm running 2.6.0.testx from BK to CVS Server on my Sony Vaio Fx 801.
I tried S4 mode ( suspend to Disk) and it works fine .


_But_ when i tried S3 suspend to ram, i got my red front light flashing 
( so it _seems_ OK)

When I tried to wake it up, i got a black screen, Backlight off, and 
kernel seemed stuck (no lan/hdd response).


I'd love to debug it, but i need some answers:

- If my laptop shuts down and has its red light blinking (normal suspend 
on ram signal)  , can i consider the kernel did correctly its work, and 
   can i assume the problem is only the resume.

- How can a faulty DSDT affect S3 mode ( DSDT compiler fired me a _WAK 
return warning). is that important ?

- What's the way to debug that ? i build a 8 Led ramp for LPT. So i can 
track the resume process through some ugly out val,0x378. Would that 
help me ?


At the moment, i'm lost 'cause i 'm not sure weather the problem comes 
from the kernel or the DSDT.


Any help, collaboration welcome!


Olivier
