I've tested each option five times with the installed 32-bit kernel (3.0.0-16.29).
reboot=w: hangs sometimes (3/5) reboot=k: hangs sometimes (4/5) reboot=t: hangs sometimes (3/5) reboot=p: works always (5/5) reboot=f: hangs sometimes (3/5) So only reboot=p (and reboot=b) reliably works. All the others hang on reboot about half the time. I'll test a 64-bit kernel next. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/950056 Title: Reboot hangs on Dell OptiPlex 780 (board 03NVJ6); reboot=bios works around To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/950056/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
