Subject: S3 resume stability problems

Hi *

I'm setting up 2 appliances based on AMD x2 4400 CPU and Nvidia Mobos: 
ASUS M2NPV-VM (6150 based) and Abit AN-M2HD (7050 based). Kernel is 
2.6.23.9.

My issue is stability of S3 resume:
-on ASUS it hangs every 3-10 try and it not depends on maxcpus setting.
-on Abit also it hangs every 3-10 try, but with maxcpus=1 is stable.

It is not depending on enabled HW on mobos - even with all HW disabled 
in BIOS S3, resume is still unstable.

Observing resume process I didn't see any errors in syslog. Also when 
resume hangs it hangs always with still lightning CapsLock keyb led 
(keyb is not reacting on CapsLock pressing) -> it leads me that it isn't 
video issue.

As Abit with maxcpus=1 is working OK - it hints me that resume issue is 
related to non-booting processor initialization.

Do somebody can help me investigate problem ?
