I experience very similar symptoms on my ThinkPad 13. It doesn't |

happen often, but it does sometimes happen. |

I noticed this as well, it's almost certainly a bug in Linux |
23 |
itself which, for some reason, has never been fixed after all |
24 |
these years. I don't think Gentoo can do much about it. |

Unfortunately I'm not aware of any real solution, but as a |
27 |
workaround, you can unmount and re-mount the psmouse module when |
28 |
the problem occurs (if psmouse is not built compiled as a module, |
29 |
I suggest you do it). At least this is what works for me, YMMV: |

|
31 |
# modprobe -r psmouse |

# modprobe psmouse |
