I'm affected too but I found a workaround on my machine !
what I did:
pierre-olivier@oneiric-Vostro-V13:~$ sudo -i
[sudo] password for pierre-olivier:
root@oneiric-Vostro-V13:~# cd /etc/pm/sleep.d
root@oneiric-Vostro-V13:/etc/pm/sleep.d# ls
10_grub-common 10_unattended-upgrades-hibernate novatel_3g_suspend
root@oneiric-Vostro-V13:/etc/pm/sleep.d# nano clavier_bug
and create the file like this:
#!/bin/bash
case $1 in
hibernate)
modprobe -r psmouse
;;
suspend)
modprobe -r psmouse
;;
thaw)
modprobe psmouse
;;
resume)
modprobe psmouse
;;
*) ;;
esac
Ctrl+O to save and choose the name you want ( clavier_bug means
keyboard_bug in french ;) )
then :
root@oneiric-Vostro-V13:/etc/pm/sleep.d# chmod +x clavier_bug
in order to make the script executable.
and
root@oneiric-Vostro-V13:/etc/pm/sleep.d# ls -l
total 16
-rwxr-xr-x 1 root root 210 2011-10-01 14:40 10_grub-common
-rwxr-xr-x 1 root root 482 2011-02-03 20:49 10_unattended-upgrades-hibernate
-rwxr-xr-x 1 root root 242 2011-10-26 15:57 clavier_bug
-rwxr-xr-x 1 root root 1260 2011-07-09 04:21 novatel_3g_suspend
to verify.
then reboot.
Trying suspend to ram or disk or close/open the lid ... and no more
keyboard issue here .
