The kernel can start up properly but the tty0 doesn't exist under /dev. I have already enable the virtual console during kernel configuration. is it something configure not properly for the kernel??

Create it with the mknod command : # mknod /dev/tty0 c 4 0 Then put the good rights, for example: # chmod 640 /dev/tty0 That should do it...

Or at least you should something like this at the output of $ grep CONFIG_SERIAL_CONSOLE /where-your-kernel-sources-are/.config CONFIG_SERIAL_CONSOLE=y $ But be aware of: "If you don't have a VGA card installed and you say Y here, the kernel will automatically use the first serial line, /dev/ttyS0, as system console." This is from HELP command in menuconfig... I'll hope this will help...
