screen shot

I tried to use netconsole and serial port. 
Our usb network card doesn't not support netconsole.
Attach serial port, system boots fail, and stop at below lines:
[   28.646597] dracut: Switching root
[   28.723991] random: init urandom read with 78 bits of entropy available
[   28.821374] init: plymouth-upstart-bridge main process (2710) terminated
with status 1
[   28.917644] init: plymouth-upstart-bridge main process ended, respawning
[   29.003485] init: plymouth-upstart-bridge main process (2720) terminated
with status 1
[   29.099711] init: plymouth-upstart-bridge main process ended, respawning
 * Startin

Attachment is the screen shot, looks like it's about OOM killer.
