After sleep (pm-suspend), messages appear when typing (probably when touching keyboard or touchpad):

While this is going on, keyboard input may miss some make- or break-strokes.
My instance (INCLUDES WORKAROUND):
HP Pavilion dv7-6175us (model LW172UA#ABA)
Ubuntu 12.04 x86_64

Worked around this by doing:
$ sudo rmmod psmouse; sudo insmod /lib/modules/ $(uname -r)/kernel/ drivers/ input/mouse/ psmouse. ko
resulting in:
kernel: [ v ] psmouse serio1: synaptics: TouchPad model: 1, fw: 7.5, id: 0x1e0b1, caps: 0xd00073/ 0x240000/ 0xa0400 platform/ i8042/serio1/ input/input15
kernel: [ v + ~52ms ] input: SynPS/2 Synaptics TouchPad as /devices/
Note that `modprobe psmouse` does not work, it apparently won't notice the presence of the hardware ???
