printk

I am debugging a driver for linux (specifically ubuntu server 9.04), and there are several printf statements in the code.

Where can I view the output of these statements?

EDIT1: What i'm trying to do is write to kernel using the proc file-system. The print code is

static int proc_fractel_config_write(struct file *file, const char *argbuf, unsigned long count, void *data)
{
    printk(KERN_DEBUG "writing fractel config\n");
    ...

In kern.log when I see the following message when i try to overwrite the file /proc/net/madwifi/ath1/fractel_config (with varying time of course).

[ 8671.924873] proc write 
[ 8671.924919]

Any explainations?
