BUG: result of insn!=insn.n

Dear all,

I use linux-2.4.17 with patch-2.4.17-rthal5g, comedi-0.7.66, 
comedilib-0.7.19, and rtai-24.1.11.
When I tried the test program named "tests" in directory /rtai/comedi_lxrt/, 
the following error message occured in kernel space:

and in user space following message occured:

synchronous test...ok

what does that bug mean? Is there anything wrong with the driver?

The modules I have loaded are:
rtai.o, rtai_sched.o ,rtai_lxrt.o, rtai_shm.o
comedi.o, kcomedilib.o,
multiq3.o (driver of my data acquisition board)
rtai_comedi_lxrt.o

and another newbie question:
what does the "comedi_test.o" in \comedi\comedi\drivers\ do? I know it 
suppose to output some signals, but after I inserted that module, nothing 
happened at all?


Thank you very much,

Xiaoyu Duan
