Re: printk's - i dont want any limit howto?

[Ram <vshrirama@gmail.com>]

Hi,
  Actually even though the printks are getting executed.

  ONLY some appear. I have given both KERN_ERR and KERN_DEBUG


   Its not the log level problem. probably the buffer or something else.
   am not sure on that.

   i have given printk_ratelimit_burst= 1000 ; printk_ratelimit_jiffies = 0 ;


   but it does not work.


   Please Advice,


   Regards,
   sriram
