This bug does not affect me anymore (at least at present, I mean ;-) and seemed related to the wake on ring feature in my BIOS settings, and to my external modem. Here is what I found:
- The Wake On Ring function in the BIOS settings was enabled and the bug was present - I turned on the system, accessed the BIOS settings, pressed the power button, and the computer restarted instead of shutting down - I disabled the W.O.R. function, rebooted the system, accessed the BIOS settings, pressed the power button, and the computer shutted down correctly - I re-enabled the W.O.R. function, rebooted the system, accessed the BIOS settings, pressed the power button, and the computer restarted instead of shutting down - I turned off my modem (external 56k) using its hardware switch on the back, turned on the system, accessed the BIOS settings, pressed the power button, and the computer shutted down correctly - I turned on my modem, turned on the system (well, actually it turned on by itself when I turned on the modem, but this was expected to me), accessed the BIOS settings, pressed the power button, and the computer shutted down correctly (!) Trying the above steps (i.e. without loading Ubuntu) makes me turn out that Ubuntu was not involved (at least afaik) - I turned on the system, loaded Ubuntu, logged in as usual, told it to power off as usual, and the computer shutted down correctly. - I waked the computer by ring as usual (Wake On Ring was actually enabled at the beginning because I sometimes use it), loaded Ubuntu, logged in as usual, told it to power off as usual, and the computer shutted down correctly. All of this make me feel the bug is not O.S. related, although I began to experience it just after upgrading to Maverick. This confuses me a (lot) bit. At a first glance, it seems that the culprit was something related to the modem switch, because turning it off and on seems to have solved the problem. But I can't say anything more about it. Does anyone else have any idea? Do other people experiencing this bug have any "Wake on..." stuff enabled in their BIOS settings? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/672298 Title: OS won't SHUTDOWN, it cycles and restarts instead -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
