Your kernel command line seems to be

   root=/dev/hda3 vga=0x317    resume=/dev/hda2 splash=silent showopts initrd=/initrd-

which does not tell the kernel to output messages on the serial console,
thus the output stops there.

Try adding 'console=tty0 console=ttyS0,115200' or similar to the kernel
commandline, and see if it helps.
