ACPI issue (Chaintech 7NIL1,Nforce2 SPP+MCP)

[ferrante]

Hello fellows,

here is this one:

the problem is that under Windows XP SP2 or SP3rc

when you put the board in suspend-to-ram (i.e. S3,STR) mode,at first seems okay but after say 4 minutes it wakes up out of the blue and any further attempts for the windows to put it to suspend are unsuccessfull->windows goes down,blanks screen etc.,but the board wakes up instantly.

Here I provide Board and BIOS info, and some useful details;

Manufacturer: Chaintech
Board:7NIL1 (produced in 2003)
Super I/O: ITE 8712F rev 5
BIOS Model: Phoenix - AwardBIOS v6.00PG
BIOS Date: 06/23/2005 (unified version- as the board had two versions C17 and C18D, BIOSes finally merged into one ver.)

Chipset: NForce 2 SPP + MCP (4-ch audio,modem,ethernet)
Chipset drivers for XP: latest applicable for NForce2 series
Audio Codec chip: 4 channel CMI 9736

Best regards,
ferrrante

disable wake on lan and wake on ring for starters

[ferrante]

Disabled everything

LAN/MODEM

wake over USB


what else??

Some of the Interrupts on Power management monitor list comes to my mind

Hmm or any processes that don't want to be suspended, some legacy software or drivers might not know what suspending is...
