Built-in keyboard and mouse non-functional after resume

[Chris Jones]

After suspending this laptop, the built-in keyboard and touchpad fail to work at all, although external input devices (e.g. Bluetooth) function correctly as they re-connect.

(I've filed this as a new bug rather than assume it's a duplicate of either bug #385056 or bug #377260 or both, so apport information can be attached).

I have the same problem. Builtin keyboard and trackpad are not responsive after resume from suspend. Resume from hybernate is fine. Laptop model is HP Pavilion tx 2100, kernel 2.6.31-17-generic (Ubuntu 9.10).

dmesg | grep keyboard returns
[ 1.495133] input: AT Translated Set 2 keyboard as /devices/platform/i8042/serio0/input/input5

A similar complaint was filed with earlier versions of Ubuntu (https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/83243) and comment 14 (https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/83243/comments/14) suggested it could be a problem with i8042 driver which affected various Linux distributions. His solution was to unload the driver before suspend and load it on resume; I am not sure about the right way to do it so I cannot test it. Any hints will be appreciated.
