** Description changed:

  Although unfortunately I am often experiencing  X lockups with "EQ
  Overflow" in the log this is the first time I notice another sort of
  message in the Xorg log, the also already known "Error in
  I830WaitLpRing" message.
  
  The parts of log referring to the lockup are (only a couple of lines
  just to make this report easier to identify):
  
  [...]
  (II) AIGLX: Suspending AIGLX clients for VT switch
  Error in I830WaitLpRing(), timeout for 2 seconds
  pgetbl_ctl: 0x7ffc0001getbl_err: 0x0 
  [...]
  
  My system consists of an HP nx7400 with Intel 945 chipset and I am using
  an up to date Ubuntu 8.04.2 LTS.
  
  Reproducing this particular flavor of  the bug might not be that simple
- but typically one out of three clean boots I experience the lockup after
- starting video playback.

  Attached I include the Xorg log.
  
  Any suggestion for fixing this issue is welcome (unfortunately I have
  experienced it with 8.10 and 9.04 as well), I would be glad to do some
  testing as well if exact steps are pointed out.
