This bug also affects me. I use a HP Pavilion Laptop dv2872 with Ubuntu Jaunty 9.04 x64 over ext4 filesystem. The system can only be restarted turned off by pressing the power button.
I attach the Dmioutput file, and the lspci file. ** Attachment added: "dmioutput" http://launchpadlibrarian.net/27203438/dmioutput -- Jaunty & Interpid: won't power off on shutdown or reboot https://bugs.launchpad.net/bugs/326988 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
