Hi all,

Annoying issue.. my ThinkPad T61 has an iwl4965 wireless card. When I have the wireless switch on, I experience a lot of issues.. system keeps freezing..unfreezing..freezing..etc.

Sometimes, a soft lockup is logged to /var/log/messages.

psmouse.c also sometimes throws an error saying the mouse lost synchronization.

Obviously, this is causing the system to freeze for a sec and throws everything off.

This is the case with both iwl4965-firmware ver 228.57.1.21 and 228.57.2.23.

There is an updated firmware available:

although I'm not sure it will particularly help with your issue.
