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). -- Andreas Bombe
