[Disksim-users] assertion spec != 0 in lp_instantiate() [utils.c] failed

[Sivasubramanian R]

Hi,
I'm new to disksim and I'm trying to get a basic configuration set up 
with disksim 4.0
I'm simulating one disk (maxtor146g) connected to a controller. However 
when I run the disksim
command, I keep hitting the following assertion failure in lp_instantiate()
"assertion failed: in lp_instantiate() (util.c:585): spec != 0: no such 
type Proc"

Could anyone help me out with this?
Thanks!
