Well i have installed the latest official driver from Realtek and
seams to have resolved some but not all.

When booting and after log in i see that theres 2 wpa_supplicant
instances running and im still with those problems, mouse hanging, and
keyboard repeating, but if i kill the wpa_supplicant triggered by
initscripts and stay only with the wpa_supplicant instance triggered
by NetworkManager than the mouse and keyboard behave fine.

So the initscript that calls wpa_supplicant is
/etc/sysconfig/network-scripts/ifup-eth and runs:

wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant.conf -D wext

and seams due to this instance that mouse and keyboard continue with
that weird behaviour.

Can anyone comment?
