What module parameters did you pass to kgdboe and what kernel are you
using and are you using the kgdb source forge patches?
I had not looked to see if anything changed in the latest net poll api,
but previously with the 2.6.21 kernel as example, the net poll api
ignored the source port parameter entirely. If this has changed, I
would be happy to make a further change to zero out the port or do what
is needed to make it dynamic again, in a similar fashion to the way the
MAC address parsing is dynamic for KGDB + the net poll api.

Also you can omit the linux-kernel mailling and take this up at:
[email protected] if you are using the source forge
patches.
