I wouldn't ask the supplier to provide a "real time version of the driver". I would ask them to provide a correctly written Linux driver that works on a current kernel version and can be submitted to Greg KH's driver project. And I would ask the supplier to contribute to the project and collaborate with Greg to make the driver ready for mainline. If it still crashes under PREEMPT_RT, then the driver is simply buggy - it just happens that the bugs do not show up or show up less frequently on the standard mainline kernel. Carsten.
