I have Compaq CQ61-420US (64-bit AMD) laptop with Synaptics touchpad checked using$ egrep -i 'synap' /proc/bus/input/devicesN: Name=SynPS/2 Synaptics TouchPadBut recently after Arch Linux 3.15-1 stock kernel, I have a lot of these messages in my dmesg accompanied with mouse freezes:[    7.064589] psmouse serio1: synaptics: Touchpad model: 1, fw: 6.5, id: 0x1c0b1, caps: 0xa04751/0xa00000/0x0, board id: 3655, fw id: 428212[11981.973831] psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1[11981.975792] psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1[11981.977503] psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1[11981.986308] psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1[11981.988072] psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1[11981.988084] psmouse serio1: issuing reconnect requestAnd after I remove and reinstall psmouse through modprobe as mentioned here on the Arch Linux Wiki# modprobe -r psmouse ; modprobe psmouseI get in dmesg:[12012.349197] psmouse serio1: synaptics: Touchpad model: 1, fw: 6.5, id: 0x1c0b1, caps: 0xa04751/0xa00000/0x0, board id: 3655, fw id: 428212`Even though the mouse starts working, but even a short amount of inactivity it gets disabled, and I have this every now and then... sadAlso I downgraded synaptics & evdev to previous versions as of now.  I also tried using:# modprobe -r psmouse# modprobe psmouse proto=imps# sudo modprobe psmouse proto=barebut none of them work!I also tried changing the CPU governor to USERSPACE which was originally PERFORMANCE, no luck even then.P.S: I also posted my problem on ArchLinux Forums.
