I have the same problem that my system reboots when I want to power it off. Rebooting is independant whether I use the KDE shutdown button or the "shutdown -P now" command on the command line.
This behaviour is also true for Ubuntu 7.04. There I had the same problem. To give more helpfull informations I attached several log file. On your web page (https://wiki.ubuntu.com/DebuggingACPI) I found some dubugging informations which I also tried, Here is a short summary about the results: acpi=off (S) acpi=ht (S) pci=noacpi (R) pnpacpi=off (R) noacpi (R) nolapic (P) where (R) : System reboots instead of shutting down (S) : System stops and can be switch off by hand (which I suppose is correct since acpi is disabled) (P) : System powers off as expected (but my USB mouse was not working with this booting option) Hopefully I could give you helpful informations for solving this bug. Don't hesitate to ask me further questions and feel free to contact my when I can help you to fix it. ** Attachment added: "dmesg.log" http://launchpadlibrarian.net/10690614/dmesg.log -- Shutdown results in a reboot https://bugs.launchpad.net/bugs/151969 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
