Could you please find out which particular test case does it? it can be 
done manually the following way:
insmod ltp_pci.ko

Get your ata bus and pci slot number, then write it to the file (the 
number is 16bit unsigned integer, the first 8 bits is a device number, 
the last is a bus number):

echo "number" > /sys/devices/ltp_tcpi/bus_slot

Then try test-cases one by one:
echo 1 > /sys/devices/ltp_tcpi/tcase
...
echo 17 > /sys/devices/ltp_tcpi/tcase

You can check the result of each test case by reading 
/sys/devices/ltp_tcpi/result file. 0 - PASS, 1 - FAIL.

Thanks,
Alexey
