I've been busy trying to bring the port back in sync with current.
Now, each time I start my NetWinder, I get the following panic which
I don't seem able to track the source. I would greatly appreciate if
anybody knowledgeable with the UMA subsystem could give me a hint on
what could be causing this.
Panic information:

Here's a trace of the calls leading to the panic

If any other information is needed (code, memory dumps, etc...)
don't hesitate to ask.
Thanks in advance!
