All, I'm facing the same problem since yesterday. The trackpoint (I don't use touchpad) just freezes on my Thinkpad T420 running 12.04 and 3.2.0-57-generic-pae kernel. After reading the entire thread, I also tried Gero's suggestion but it didn't work for me. For the first time (when trackpoint froze yesterday) i got the similar errors in dmesg and syslog like: Dec 17 13:51:55 vipin-thinkpad-t420 kernel: [13612.139398] psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 But today, the trackpoint froze for 3-4 times and such errors are not seen in logs. I also noticed that this happens when I'm typing and want to use trackpoint immediately after that. Strangely, I'm using this laptop (with same OS) since last 1+ year, this problem started to happen since yesterday only. And now it is happening everytime in only 5-10 mins after reboot. Just wanted to give an update on my problem, so anyone working on this problem currently?
