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 ?

Please file a bug report at
http://bugzilla.kernel.org/enter_bug.cgi?product=Power%20Management
against the Hibernation/Suspend component and add my address to the report's
CC list.
Thanks,

Try starting/stopping cpus in loop, to see if cpu hotplug works
reliably.
