ACPI Sleep problem

ACPI Sleep problem

[Manuel Arguelles]

Hello list,

I have a laptop, dell latitude d810, running slackware linux 12.0, kernel: 
2.6.21.5 (vanilla as far as i know).

I can put it into sleep mode, but it doesn't came up, and I'm not sure how to 
debug it, I supposed it doesn't come up fully and not only the video, since 
if I wake it up, and type my loggin in and pass and type restart or similar 
nothing happends....

I have read that it's good to update teh dsdt, but from 
http://acpi.sourceforge.net/ there's only one:
