Description o. meijer 2007-10-02 05:34:34 UTC
Most recent kernel where this bug did not occur: 2.6.22.6
Distribution:ubuntu 7.04, custom vanilla kernel
Hardware Environment: Laptop NX5000 
Software Environment:Linux, X
Problem Description:
When using the evdev driver in xorg, see snippet of xorg.conf,a kernel oops occurs when unplugging the mouse.

Steps to reproduce: Low latency dektop, always when unplugging the mouse(both, Logitech+microsoft wireless), hard locks randomly but not very often when moving the mouse. (the problem only occurs when using the xorg-evdev-driver)

snippet of xorg.conf:
Section "InputDevice"
         Identifier "Logitech"
        Driver "evdev"
        Option "evBits"  "+1-2"
        Option "keyBits" "~272-287"
        Option "relBits" "~0-2 ~6 ~8"
         Option "Pass"    "3"
      EndSection

Comment 1 Dmitry Torokhov 2007-10-02 06:33:32 UTC
Any chance you could try -mm? The input core lockign patches are there and are scheduled to be merged in mainline when 2.6.24 opens up.
Comment 2 Andrey Melentyev 2007-11-08 11:41:27 UTC
The bug is also reproducable on my system:

Dmitry, you say that patches should be merged in 2.6.24, are they already in 2.6.24-rc2? I could try it then.
Comment 3 Dmitry Torokhov 2007-11-08 11:59:32 UTC
They are in both 2.6.24-rc1 and 2.6.24-rc2
Comment 4 Vlastimil Babka 2007-12-12 01:59:53 UTC
Hi,

got exactly the same problem with 2.6.23, and seems that it's fine in 2.6.24-rc4.
Comment 5 o. meijer 2008-01-27 14:20:14 UTC
solved with 2.6.24 for me
