Actually I added it to the defoptions line: # defoptions=quiet reboot=pci and after running 'update-grub', I have: title Debian GNU/Linux, kernel 3.4-trunk-amd64 root(hd0,0) kernel /vmlinuz-3.4-trunk-amd64 root=/dev/mapper/xvii-root ro quiet reboot=pci initrd /initrd.img-3.4-trunk-amd64 title Debian GNU/Linux, kernel 3.4-trunk-amd64 (single-user mode) root(hd0,0) kernel /vmlinuz-3.4-trunk-amd64 root=/dev/mapper/xvii-root ro single initrd /initrd.img-3.4-trunk-amd64 [...] The kopt line is: # kopt=root=/dev/mapper/xvii-root ro so that if I added the option to kopt, I suppose that it would be added to the single-user mode entries too (as documented). However I never have to use single-user mode. :) dmesg confirms that reboot=pci is taken into account: [0.00] Command line: root=/dev/mapper/xvii-root ro quiet reboot=pci I just did a single reboot with this, and it was fine. The future will tell whether this really solves the problem.

The future will tell whether this really solves the problem. Ok, awesome. Thanks to both of you. The DMI list in arch/x86/kernel/reboot.c (including Latitude E6420, etc but not E6400) is really disheartening[1]. Matthew Garrett mentioned it recently at [2]. Does disabling VT-d in the BIOS help? (To avoid confusion for people listening in: this is meant as a diagnostic question and not intended as a fix.)

Hi Vincent, Vincent Lefevre wrote: When I want to restart (reboot) my Dell Latitude E6400 laptop, the machine sometimes remain on without restarting. The last message on the console is: Restarting system. Interesting; thanks for reporting it. Can you take a photograph of this so we can see the lines before that one? The problem doesn't always occur. I don't know the conditions. Perhaps when the laptop has been suspended and resumed previously. Please attach acpidump output. If you can get full dmesg output from right before a successful and an unsuccessful reboot, that would be interesting, too. Hope that helps, Jonathan -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe. Trouble? Contact listmas...@lists.debian.org

Can you try adding the following parameter to your kernel boot line? Add it to the GRUB_CMDLINE_LINUX parameter in /etc/default/grub and run update-grub. reboot=pci We need(ed) to add this parameter to some of our recent Dell desktops to make them reboot. Let us know if this helps, so it can be made the default for this laptop type. Regards, Rik -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.
