Probs in printk

[_VJ]

Hi,

I'm using printk for the device driver I'm writing.It doesn't give the 
output to my console and the only way I can get those is just using
cat  /proc/kmsg.But what I want is to get console prints while I'm 
running .Then I put the kernel image of the remote system where it used 
to give console output.Still I'm not getting any output to the screen.I 
tried to use console_print ....not giving any result to the console.So I 
would like to know what can I do about this

Thanx in advance.

Vj

The only time that I've had this kind of problem (that I recall),
I just had to use a KERN_printklevel attribute to print the message.
E.g.,
	printk(KERN_CRIT "where does this message go\n");

It can also help to change the console loglevel (Alt-SysRq-N, where
N is 1 digit, higher prints more messages [try 9]).

and what kernel version?  You should always give that info,
even when it's useless.  :)
