Hello, I have written some code using rtai + comedi to get data from some sensors. I am trying to use this code with your quatech driver but it does a segmentation fault when I make a comedi read from the any analog input chanel. My code works OK with an advantech 1710 card so maybe the problem is in your driver. Analog output seems to work OK however. Going deeper in the quatech driver I have found that what makes the program fail is the "down_interruptible" call in the analog read function. Does anybody know if is a comedi or a kernel problem (I have tried with several kernel versions so the kernel should not be the problem). Is it possible that I cannot call down interruptible from rtai? Any help would be much apreciated. Thanks in advance, Luis Martinez
