Sounds good. If you can capture the error as Daniel suggests, that would
be great. In any case, I'll post a revert of the semaphore enable patch

Hi,
With Linux-3.2-rc6 I'm frequently seeing GPU hangs when large amounts of
text scroll in an xterm, such as when extracting a tar archive. Such as this
one (note the timestamps):

GPU hung
