I'm using the intel driver from unstable (2.7.1), and I have not noticed
the problem.
2.7.1 also fixed other hangs I often noticed with 2.7.0. The fix was
probably this change:
* Fix multiplication error when computing required batch space.
This could fix any number of cases where the driver did
inexplicable things (due to having computed the wrong
size). [Keith Packard <keithp@keithp.com>]
