Public bug reported:
Binary package hint: linux-source-2.6.22
On Samsung Q1 ultra, the linux-image-2.6.22-10-generic S3 (suspend to
ram) has a very interesting phenomenon: it seems lose OS timer
interrupts and needs external interrupts to keep kernel running.
I installed pm-utils and vbetool, used: pm-suspend --quirk-vbestate-
restore to enter S3, after that, system went sleep, after triggered
power button, system seemed to recovery, but I needed keep pressing Q1's
keyboard to trigger system scheduling. For example, ran a "top" program
in the console, the "top" would keep idle until I press anykey, and the
manner would be "press one time, top run one time". Even for "ls -al", I
needed to press key extra times to let it go. Beside key pressing, other
events like plug in/out power adaptor could trigger system too.
In one short sentence, the world was now triggered by external
interrupts.
