Title:
  X11 freezes, sshd working, chvt 1 very slow

Status in linux package in Ubuntu:
  Expired

Bug description:
  I'll attach kernel oops information after I've reboot the laptop.

  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.
