This problem also occurs when I run 'ifconfig wlan0 down'. It freezes the system for 2-4 seconds. This does not happen when I bring the interface back up.

This is dmesg after I run 'ifconfig wlan0 down':
# dmesg
iwlagn: index 255 not used in uCode key table.
psmouse.c: GlidePoint at isa0060/serio1/input0 lost synchronization, throwing 1 bytes away.
iwlagn 0000:0e:00.0: PCI INT A disabled
psmouse.c: resync failed, issuing reconnect request

My mouse disappears when I run that command (and any music playing at that time will loop until the system 'unfreezes').

Confirmed, but here with iw4965. Same thing happened on Ubuntu (8.04, 8.10). It is something about driver. It's buggy.
