Re: opcontrol error

[Marlena M. <mar...@ho...>]

I added debug to the opcontrol script and discovered that I was missing the 
objdump binary.

In addition, it looks like the kernel.vmlinux file is different from the 
<BlueCat linux tree>/usr/src/linux/vmlinux file. When I copy over the 
vmlinux file from the BlueCat linux tree, it works fine.

Thanks,
Marlena
