When I load the matis driver (using Technisat SkyStar 2) my system randomly locks completely. Sometimes it takes days to the next lockup but sometimes it happens several times in 10 minutes. It looks like it happens even if I only load the driver without starting any applictions that use the adapter. Since I have to press the reset button I do not have any logfile information. I had this behavior with kernel 2.6.33 and 2.6.34 too.
