I want get kernel debug printk() message over netconsole especially when machine hangs.
when put following in kernel comand line
netconsole=4422.214.171.124.1/eth1,9353 at 10.0.0.2/12:34:56:78:9a:bc
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 10.0.0.1/eth1,9353 at 10.0.0.2/12:34:56:78:9a:bc
Then I try to load/unload wifi driver that has something printk() messages but nothing appears on remote PC.
Any idea for that?
