Hi! My system doesn't shut down properly. Kubuntu Dapper 6.06 LTS (packages updated regularly) Current kernel image of 2.6.15-26-686 Mainboard: MSI 865PE Neo2-P Processor: Intel Pentium 4 2.8E GHz 800 MHz (Box) RAM: 3 x 512 MB DDR Video card: NVidia GeForce 5200 FX Keyboard: Logitech iTouch Internet Graphics tablet: Wacom Intuos A5 I remember having the same problem under Debian 3.0, but as that encounter was somewhat short and is about a year ago, the only thing I can remember is that it was a 2.6 kernel as well. Kubuntu also claims that I have a partial ACPI installation ("not fully installed" or something the like in "System Settings -> Laptop and Power -> Laptop Battery -> Power Control"). This is probably related to "acpi -V" producing the error message "No support for device type: thermal" and having almost no useful entries in "/proc/acpi/...". When I remove the boot option "quiet splash" I get the following messages during shutdown: * Will now halt. [...] md: stopping all md devices [...] usb 4-2: new full speed USB device using uhci_hcd and address 3 [...] usb 4-2: not running at top speed; connect to a high speed hub [...] Shutdown: hda [...] ACPI-0517: *** Error: Method parse/execution failed [\SB_.PCI0.IDE0.GTM_] (Node dffe5d60), AE_AML_PACKAGE_LIMIT [...] ACPI-0517: *** Error: Method parse/execution failed [\_SB_.PCI0.IDE0.CHN0._GTM] (Node dffe5fa0), AE_AML_PACKAGE_LIMIT [...] Power down. [...] acpi_power_off called Then there's a click as my hard drives shut down, and that's about as near as I ever get to shutting down my computer. The only thing working at this stage are pressing the power button (for unusual 4 seconds) or the reset button. Also, when I reboot the computer from KDE, it does as told, but when in the BIOS routines, there's a noticeable pause and a click when my two S-ATA drives are checked. I don't have a problem like that when rebooting Win XP (I have a dual boot system). I had a look at several forums and had a go at fixing my DSDT.dsl (you can find the original file at http://www.ubuntuusers.de/paste/2441/?format=txt). As running the recommended cp /boot/initrd.img-`uname -r` /boot/initrd.img-`uname -r`-acpifix echo -n "INITRDDSDT123DSDT123" >> /boot/initrd.img-`uname -r`-acpifix cat /boot/DSDT.aml >> /boot/initrd.img-`uname -r`-acpifix failed to produce a bootable image, a found a workaround (and I'm a little proud, being still new to Linux... <g>): sudo cp ~/DSDT.aml /etc/mkinitramfs/DSDT.aml sudo mkinitramfs -o /boot/initrd.img-`uname -r`-acpifix After rebooting with such an image I find this in the syslog: [...] ACPI-0284: *** Info: Table [DSDT] replaced by host OS [...] ACPI: Looking for DSDT in initramfs... found /DSDT.aml ... successfully read 13614 bytes from /DSDT.aml [...] ACPI: Using customized DSDT As this message vanishes when I run an original image, I think it has worked. Es scheint also geklapt zu haben. Zeit, sich dem Problem zuzuwenden - ein Lauf von iasl -sa DSDT.sdl ergibt die folgende Meldung: So here are the warnings I found when recompiling the DSDT: Intel ACPI Component Architecture ASL Optimizing Compiler version 20060707 [Jul 25 2006] Copyright (C) 2000 - 2006 Intel Corporation Supports ACPI Specification Revision 3.0a DSDT.dsl 4034: Method (STM, 0, Serialized) Warning 1086 - ^ Not all control paths return a value (STM_) DSDT.dsl 4359: Method (_WAK, 1, NotSerialized) Warning 1079 - ^ Reserved method must return a value (_WAK) ASL Input: DSDT.dsl - 4458 lines, 150438 bytes, 1514 keywords AML Output: DSDT.aml - 13606 bytes 500 named objects 1014 executable opcodes Compilation complete. 0 Errors, 2 Warnings, 0 Remarks, 462 Optimizations For the second warning I use the googled "standard solution" Return(Package(0x02){0x00, 0x00}) So the problem seems to lie within the first warning. As my machine code knowledge is based on the Z80 and was lost somewhere years ago, I'd like to ask for your help. I also checked the WWW and the ACPI spec for ideas, but couldn't come up with anything useful. Any help is deeply appreciated!
