I have the same problem with a DELL precision T5400. I googled a bit and I think there has been a patch submitted for it. http://bugzilla.kernel.org/show_bug.cgi?id=11108
My guess is that this is the same as adding 'reboot=b' to the grub kernel line. -- dell dimension 9200 - reboot doesn't work https://bugs.launchpad.net/bugs/131292 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
