I have 2-finger scrolling set up on my touchpad, using GNOME settings. After running my laptop for a while (several hours), such scrolling is no longer functional, and the touchpad itself is rather unstable (barely usable). Here's the output from syslog:Nov 15 21:07:06 tshepang kernel: [40639.175677] psmouse.c: TouchPad at isa0060/serio4/input0 lost sync at byte 4Nov 15 21:07:06 tshepang kernel: [40639.177708] psmouse.c: TouchPad at isa0060/serio4/input0 lost sync at byte 1Nov 15 21:07:06 tshepang kernel: [40639.191630] psmouse.c: TouchPad at isa0060/serio4/input0 - driver resynched.Nov 15 21:07:07 tshepang kernel: [40639.503288] psmouse.c: TouchPad at isa0060/serio4/input0 lost sync at byte 1Nov 15 21:07:07 tshepang kernel: [40639.505326] psmouse.c: TouchPad at isa0060/serio4/input0 lost sync at byte 1Nov 15 21:07:07 tshepang kernel: [40639.507310] psmouse.c: TouchPad at isa0060/serio4/input0 lost sync at byte 1Nov 15 21:07:07 tshepang kernel: [40639.509479] psmouse.c: TouchPad at isa0060/serio4/input0 lost sync at byte 1Nov 15 21:07:07 tshepang kernel: [40639.511280] psmouse.c: TouchPad at isa0060/serio4/input0 lost sync at byte 1Nov 15 21:07:07 tshepang kernel: [40639.511285] psmouse.c: issuing reconnect requestNov 15 21:07:07 tshepang kernel: [40640.198742] Unable to query Synaptics hardware.I'm on Debian Unstable, currently with Linux 3.1. The problem is reproducible with Linux 3.0. I haven't tried any other kernel. Reloading the psmouse module (sudo modprobe -r psmouse && sudo modprobe psmouse) doesn't help, forcing me to reboot the machine. I'm wondering if this could be a hardware problem.
