Recently i do some benchmarking in the FreeBSD OS, and today i decide to enable some performance tools in the kernel which can be realized by building a new kernel. Before that, i refer to the FreeBSD handbook for howto. It says that if i fail to load the new kernel, we can select the "escape to a loader prompt" option. By loading the correct kernel, we can reboot the system. However, problem happens. When i select the "escape to a loader prompt" option, i can input in about just 3 sec. After that, the system cannot go on whatever key i hit. The whole system have 4 hard disks; and i install 3 OSes in the first 3 hard disks which are Linux, Solaris and FreeBSD in order. All systems are booted using grub. Any ideas? Best Wishes! Yan
