I think that's different as firmware started to > support XB143 only starting from 10.1.467. 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 :) Thanks, Ben -- Ben Greear Candela Technologies Inc http://www.candelatech.com
