Re: suspend breakage vs android 2.2 bootloader?
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.
