I will investigate. Could you please :
- Load the module
- Show me the output of lsmod
- Use your ethernet a bit
- Try to unload the module
- If your board did not freeze or if your kernel did not panic , show
me your dmesg (if it is impossible show me the dmesg before unloading
Perhaps, we could continue this discussion in private (by email or
IRC). What do you think ?
I will investigate this evening and tomorrow. Thanks for your feedbacks .
