psmouse serio1：isa0060/serio1/input0 处的 DualPoint TouchPad 失去同步，抛出 2 个字节

Question

最近我的 DELL Vostro 3750 笔记本电脑出现了问题，触摸板行为不稳定。

查看dmesg输出我可以看到：

[175874.428170] psmouse serio1: DualPoint TouchPad at isa0060/serio1/input0 lost synchronization, throwing 5 bytes away.
[175874.938670] psmouse serio1: resync failed, issuing reconnect request

在网上查找，似乎发生了最近的 Linux 内核，但我仍然使用同一个内核：

$ uname -a
Linux maester 3.14-0.bpo.1-amd64 #1 SMP Debian 3.14.12-1~bpo70+1 (2014-07-13) x86_64 GNU/Linux

如果我打开 debugfs，我会看到以下内容：

# cat /sys/module/psmouse/parameters/proto
auto
# mount -t debugfs none /sys/kernel/debug/
# echo "file drivers/input/mouse/* +p" >  /sys/kernel/debug/dynamic_debug/control

我已经将我的系统更新为 debian/jessie 系统，但一切仍然无法正常工作。

在玩了i8k模块之后，我意识到这i8kmon是按预定间隔运行的。我决定停下来并且手动删除模块i8k。出于某种原因，黑名单是不够的：

$ cat /etc/modprobe.d/i8k-blacklist.conf
# https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=732242
blacklist i8k

触摸板现在运行良好，键盘不再出现问题。甚至风扇也以正确的速度转动（以前它会无缘无故地启动/停止）。
