Comment # 45 on bug 1172951 from Takashi Iwai

Thanks.  It showed the same error, and the downstream patch didn't help in this
regard, unfortunately.

For fixing further this in the kernel, you need to report the issue to the
upstream bug tracker, e.g. bugzilla.kernel.org, so that the upstream devs can
work on it.  But I'm afraid that it won't be addressed soon enough, as the bug
is very specific to the machine.

And, it's possibly a bug of the touchpad device firmware.  Often you can
upgrade the firmware, but it might need Windows.

Last but not least, after suspend/resume and the dead touchpad, try the
following on a terminal (as root):

modprobe -r rmi_smbus
modprobe rmi_smbus

It might revive the touchpad.
