how to debug the linux kernel with a BDI2000

[jxnuxdy]

My kernel hanged in when passed the parameters to it, and I dump nothing from the log_buf, so I guss it is crashed at the very beginning. however I didn't know how to setup the KDB to load the kernel with the BDI2000 ethernet? is there anyone has even loaded and debugged the kernel with the BDI2000 ethernet? if so pls show me how it goes?  ,Thanks- Denny
