[Prism54-users] ifconfig kernel oops

[Ronald Bock]

A wonderful friday to everyone,

I just compiled cvs snapshot 20031205 5:00 
After bringing the driver into master mode I issued 
an ifconfig on eth1 which resulted in an oops and a stalled machine.

The system is our mipsel based board running with kernel version 2.4.23-rc5
We are using mini-pci cards in our cubes.

This error might be related to the NOCACHE versions of the MGT Functions 
defines , but  I have to look closer at the changes this afternoon.

I will try to reproduce this error after lunch, which did not occur with the 
yesterdays snapshot.

Brgds Ronald
ps: It is fun to watch this drivers growing. I think that the team is doing a 
very good job.

Here are the results of the ksymoops output:
