Could you please try the patch below - it should fix the issues you are
seeing although there may be other devices (really any hot-pluggable
device) that will show the same behaviour. In the long run swsusp should
not attempt resuming devices when the system can not handle the process



Input: serio - do not attempt to immediately disconnect port if
resume failed, let kseriod take care of it. Otherwise we
may attempt to unregister associated input devices which
will generate hotplug events which are not handled well
during swsusp.
