   Hello,

   Yes, the machine can wake up with pure head src + this patch.

   The machine I'm using is a cheap mobile notebook with a ULV CPU.
 It does not have a serial port and a firewire. I have USB-serial
 adapters, but I don't think it helps to make a serial console.
 I can only take a memo by a pen, if the machine does not reboot
 immediately and the keyboard on DDB is alive.
