Bug Description

Environment
Using Hardy development branch with latest updates. System version described in attachment.

Description
after resuming from Suspend, my mouse won't work. This happened several times (not sure if it happens every single time as I avoid suspend/hibernate due to various small issues).

Details:
1. resume from suspend

What happens
 mouse doesn't work
 following message appears in dmesg:
   "i8042 failed to resume active multiplexor, mouse won't work"

Expected:
 working mouse :)

I believe the problem lies in the kernel package. Cannot select it due to mouse issue...
