Yes.  My point is that I have the ability to get debug info out of
of the otp in my modified firmware, so it is possible to debug why
the otp is failing in the first place, and possibly fix otp to work
with that NIC.

I'll start begging to get my CT firmware support in upstream kernels
as soon as we get the firmware-crash stuff ironed out :)
