Description Tim Roes 2012-10-12 19:59:23 UTC
When I try to start a virtual machine out of VirtualBox my Xserver hangs. I can still move the mouse around, but nothing else is working.

Xorg.log shows a lot of 'EQ overflows' (see attached file).

As soon as I remove my wacom mouse (that only works ON the wacom tablet) from the tablet, xserver continue to work.

This may be more of an issue with Xorg that is much more widespread than just VirtualBox and Wacom.  I just encountered this "EQ Overflow" bug with Xorg after a world update running nvidia-drivers-337.25.  

Here is the 'emerge --info', and I will follow up with the Xorg.0.log.

20140630: Xorg.0.log

The Xorg.0.log showing the start of the hanging at ~3.2 days (e.g. 278556 secs.).

In this Xorg log, the trace seems to point to evdev_drv and/or nvidia_drv.

Is this still a problem on current versions?
