I have discovered a serious bug where Ubuntu wakes up the system from ACPI S3 State instantaneously if I am using a system with SiS chipset's USB.
This bug seems to have started with Ubuntu 12.04 LTS (3.2 Linux kernel) because it didn't exist in Ubuntu 10.04.4 LTS 32-bit (2.6 Linux kernel).
As far as I know, this bug occurs with SiS 963 and 964 southbridges.
I observed this bug with ASUS P4S8X (SiS 648/963) and ASUS P4S8X-MX (SiS 661GX/964) mainboards.
WORKAROUND:
The problem will go away if I disable SiS chipset's USB in BIOS setup.
WORKAROUND: Execute these commands at a terminal:
sudo sh -c "echo EUSB> /proc/acpi/wakeup"
sudo sh -c "echo USB > /proc/acpi/wakeup"
sudo sh -c "echo USB2 > /proc/acpi/wakeup"
sudo sh -c "echo USB3 > /proc/acpi/wakeup"
WORKAROUND: USB devices that are slow devices (keyboard, mouse, etc.) seems to trigger this bug.
We are talking about USB Full-Speed (FS) and Low-Speed (LS) devices here.
If USB High-Speed (HS) devices (Also called USB 2.0 devices.) are used, they don't seem to trigger this bug.
An example can be a USB 2.0 flash memory dongle.
WORKAROUND: I have discovered that ECS L4S5A/DX+ mainboard (SiS 645DX + SiS 962) is not impacted by this bug.
SiS 962 chipset implements USB 2.0 (EHCI) as well as USB 1.1 (OHCI).
So far, 2 of the mainboards affected by this bug were made by ASUS.
Perhaps, the bug can be BIOS implementation specific.
They have SiS 963 (ASUS P4S8X mainboard) and SiS 964 (ASUS P4S8X-MX mainboard).
SiS 962, 963, 964 are fairly similar to one another, especially around the USB.
