 1. Install 11.3.0 os4 on an XO-1.75.
  2. Set the "Copy" option to "false" in xorg.conf.d/xo-1.75.conf to work
 around another issue.  Restart the XO.
  3. Open the Browse activity and browse slashdot.org for a bit.

 Expected: Everything works.

 Actual: More often than not (often on the first page of the website) the
 video driver will hang, and you will not be able to switch virtual
 terminals or anything else.

 Xorg.0.log will contain the following:

 {{{
 [   446.694] (EE) dovefb(0): mrvlGeneralImageTransfer: flush GPU cache,
 1374 line
 [   472.686] (EE) dovefb(0): mrvlFencePoolStall:sync marker timeout, wait
 1, real 0
 }}}
