Serial console can be monitored for messages in the Linux kernel too....just make sure that the appropriate kernel parameters are set. Use a null-modem serial cable connected back-to-back across the serial ports of your PC. Edit the kernel command line parameters in /boot/grub/menu.lst (in Fedora) to append "console=ttyS0,115200" (other baud rates are possible too), and remove the "quiet" line in the parameter. Ensure the same is repeated on the PC at the other end. Reboot the PC and use a program like "minicom" on the host PC to connect to the target and check if serial connectivity is fine. Any subsequent boot crashes should be logged on the host PC through minicom. KGDB (not KDBG which is entirely different) is a kernel debugger and when setup (is another process altogether) can make the kernel on the target machine act like a process being debugged through GDB (the last I know about KGDB is that it is broken and the community isn't very active in resolving the issues).
