    Subject[REGRESSION] Xorg doesn't like 4e8b14526 "time: Improve sanity checking of timekeeping inputs"
    I have recently started to get problems with X simply shutting itself
    down and returning to the login screen. In the X logs I find:

    > [ 1492.936]
    > Fatal server error:
    > [ 1492.936] WaitForSomething(): select: Invalid argument

    No messages whatsoever is found in the kernel logs. This error happens
    randomly without any correlation to user input, but with a high
    likelihood (within a few minutes at most) when a video is playing. It
    doesn't matter if the video is in Flash in a browser window or in a
    video player playing a local file.

    With that somewhat easy test I bisected it down to 4e8b14526 "time:
    Improve sanity checking of timekeeping inputs". The latest Linus git
    (155e36d40) with a revert of the bisected commit does not show the
    problem.

    Video is Radeon HD 6950 with open source drivers. Xorg version is the
    one currently in Debian unstable (xserver-xorg-core: 2:1.12.3.902-1,
    xserver-xorg-video-radeon: 1:6.14.4-5, libdrm: 2.4.33-3).
