I think you missed the significance of my second paragraph above - I have
established that the hang is _not_ caused by the mis-use of the
glDrawRangeElementsBaseVertex() function. So comparing how the radeonsi and
Intel/r600 drivers handle this function is not likely to help in resolving this
issue.
