 |

I have a Thinkpad Edge11 and i'm using kernel 2.6.38 and the ibm stuff like tp_smapi. Sometimes the cursor freezes for 1,2 sec and then moves on.
When i look at dmesg i get this:

There are a lot of hits at google, some bug reports from 2007, but it still seems to occur on some systems.
I tried all the hints, for example using "acpi_osi=linux i8042.nomux=1 i8042.dumbkbd=1" as kernel operations.
I also deactivated the touchpad, as i'm only using the trackpoint. I'm using xinput for this.
This is the relevant part in my xorg.conf:

Section "InputDevice"
Identifier "Mouse0"
Driver "synaptics"
Option "SendCoreEvents" "true"
Option "Protocol" "auto-dev"
Option "Device" "/dev/input/by-path/platform-i8042-serio-1-event-mouse"
Option "EmulateWheel" "true" #Enable wheel emulation for the Trackpoint
Option "EmulateWheelButton" "2" #Use the middle button for the emulation
Option "XAxisMapping" "6 7" #Map trackpoint X axis to X axis of emulated wheel
Option "YAxisMapping" "4 5" #Map trackpoint Y axis to Y axis of emulated wheel
Option "TouchpadOff" "1"
Option "SHMConfig" "on"
EndSection

I've been having a similar issue on a Thinkpad Edge running Linux Mint 10.
I guess it's a bug in the driver / kernel, no idea how to fix it. |
