If they miss the "" around $comp_arr in the last line they will get all the values on one line which will be rejected with -EINVAL during injection. This works better (and is shorter too!): # echo -e '0x1 0x2\n0x1 0x4\n0x2 0x4\n\0' > einjv2_component_array I think explicitly terminating the input with '\0' is needed (and that the kernel should NOT zero out the einjv2_component_array blob on each injection. That's unlike the other einj paramaters which are "sticky". The user can repeat the same injection without resetting all the parameters each time, just "echo 1 > error_inject" to do the same thing again. -Tony
