Hi,

it just jumped in my mind that people with suspend problems (especially 
wakeup problems) must *not* specify lp0_vec on the kernel cmdline. This 
parameter is obsolte now.

Unfortunately, Ubuntu still specify it in /boot/bootimg.cfg sometimes. 
Please check and remove it from there and run abootimg again.

Marc
