I want get kernel debug printk() message over netconsole especially when machine hangs. 
when put following in kernel comand line
netconsole=4444.,9353 at

and put following in remote PC.
'netcat -u -l -p 9353'

When kernel is booting, I see printk() message on remote PC. But it is only good when booting.

Then I tried following after boot,
modprobe netconsole netconsole=4444 at,9353 at

Then I try to load/unload wifi driver that has something printk() messages but nothing appears on remote PC.

Any idea for that?
