** Description changed: 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). + Test System 1: - Intel Pentium 4 2.8 GHz * 800 MHz FSB * 130nm device (Northwood) * Hyperthreading enabled - ASUS P4S8X-MX mainboard * SiS 661GX northbridge * SiS 964 southbridge * BIOS Revision 0808 (last release) * Power -> Suspend Mode: S3 State (ACPI S3 State) * Legacy keyboard/mouse emulation enabled - 1GB DDR SDRAM * 512MB DDR400 DDR SDRAM module * 512MB DDR400 DDR SDRAM module - SiS 661GX integrated graphics * Using 16MB for graphics - Hitachi IC35L060AVV207-0 60GB PATA hard drive - Hitachi-LG Data Storage GCC-4481B PATA CD-RW/DVD-ROM drive - USB multi-card reader - PS/2 keyboard - PS/2 mouse Test System 2: - Intel Pentium 4 2.66 GHz * 533 MHz FSB * 130nm device (Northwood) * No Hyperthreading - ASUS P4S8X mainboard * SiS 648 northbridge * SiS 963 southbridge * BIOS Revision 1005 (last release) * Power -> ACPI Suspend to RAM: Enabled (ACPI S3 State) * Legacy keyboard/mouse emulation enabled - 1GB DDR333 DDR SDRAM * 1GB DDR333 DDR SDRAM module - NVIDIA GeForce 4 MX440 * 64MB DDR SDRAM * AGP - Seagate ST340014A 40 GB PATA hard drive - Pioneer DVR-111D PATA DVD-RW drive - 3.5" 1.44 MB floppy disk drive - PS/2 keyboard - PS/2 mouse Please fix this bug.
