I was having this same problem on my Asus M70. It would hang and beep incesently right after I saw it begin to enumerate over the USB ports; incidentily this is also right before the ubuntu loading screen is presented (which appears to be the actual cause of the problem).
In GRUB I removed the quiet and splash options and I no longer have this problem. -- System beep goes nuts on start up https://bugs.launchpad.net/bugs/255590 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
