The right link is:

http://bugzilla.kernel.org/show_bug.cgi?id=4564

bugzilla kernel 4564

Anyway it seems to be a problem of ps/2 protocol between de KVM and the MB of your system according to what i've found.

Try putting any of this parameters at the end off kernel boot line

psmouse.proto=exps or psmouse.proto=bare or psmouse.proto=imps

Also you can try unloading the psmouse module and reloading with this parameters

proto=imps resync_time=10

try using the different protocols.

Also to get the most information let's get this output as root:

- "echo 1 > /sys/modules/i8042/parameters/debug"
- switch to your other box
- wait 5 seconds
- switch back to linux box
- Press left mouse button once
- "echo 0 > /sys/modules/i8042/parameters/debug"
- upload dmesg

About the video issue i believe we would need a different bug report for that one. in the meantime i'm marking this related to upstream bug 2082 and 4564. Not exactly the same but similar enough.
