I have a 17.3" M6600. I just upgraded the BIOS from version A7 to version A9, and the problem (which had been happening 100% of the time) has gone away. This is with Ubuntu 12.04 and latest kernel.
NB: Dell only supplies the BIOS update as a Windows/DOS exe. Use netbootin to install FreeDOS to a USB drive, and copy the .exe to the drive. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/841264 Title: Dell Precision M6600 laptop hangs on reboot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/841264/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
