The bug is not reprodicible at will, but happens regularly, usually after 1 day, but this time I've reached an uptime of 5+ days. X11 freezes, the mouse pointer is updated but that's it, no updates to windows happen, nor have I've been able to detect any other effect from X11 events. chvt 1 takes very long and results in a kernel oops. chvt 7 sometimes restores the X11 session.
