Hi Henry,

I just tested a setup very similar to yours here and it works quite fine - 
have you tried setting the console log level to 8 yet?

dmesg -n 8
modprobe netconsole 
netconsole=4444 at 10.0.0.1/eth1,9353 at 10.0.0.2/12:34:56:78:9a:bc

Maybe that printk of your wifi driver is just a KERN_DEBUG message.



Best regards,
Peter
