Max number of insns in comedi_do_insnlist?

For some reason, comedi_do_insnlist() produces bogus data whenever I
specify more than 9 consecutive read instructions in the same instruction
list (reads on different channels, but still reads).  Is this due to some
limitation in the kernel side's copy_from_user() (since I understand with
a lot of instructions in an array, the size of the memory area to be
copied to kernel space can get large) or to some other limitation in
comedi?   Or am I just completely insane?

Thanks,
