Gigabyte GA-X48-DQ6 "acpi0: device_suspend failed"

[Tim Matthews]

Hi any attempt at suspending using either acpiconf -s 3 or gnome's suspend
just appends this line to the dmesg:

acpi0: device_suspend failed

Motherboard is a Gigabyte GA-X48-DQ6. Verbose mode doesn't report anything
else other than suspend failed line. Shutdown & reboot work fine.

I have run these commands and attached the resulting files if that means
anything to anyone:

acpidump -dt > tim-x48dq6.asl | bzip2 - > tim-x48dq6.asl.bz2
sysctl -a | grep -i acpi > tim-x48dq6-sysctl.txt

Thanks
