>Description:
Asus S5200N (similar as Asus S5N). i855GM chipset.
FUJITSU MHT2040AT hdd.

Tests was made in the running netbsd-4 with minimal running processes.

When i disable USB in bios after setting machdep.sleep_state=3 
i'm getting messages:
acpiec0: timeout waiting to EC to respond to EC_COMMAND_QUEURY
acpiec0: GRE command failed AE_ERROR

when USB is enables there is no such errors.

# sysctl -w machdep.acpi_vbios_reset=0
no messages
# sysctl -w machdep.sleep_state=3
acpi0: entering sleep state 3
...and notebook goes to sleep
after a pressing power button i see:

acpi0: good morning
ioapic0: enabling

and then nothing. Machine hangs.

Notebook is very quite. No cooler or hdd sounds.
it seems that hdd is not enabled after waking up.

Let me know if a can provide any additional information.
>How-To-Repeat:
sysctl -w machdep.acpi_vbios_reset=0
