initrd stage: No printk debug message

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,
I want to debug a driver during boot time.  I have  tried putting
KERN_EMERG/ERR/ in module_init  call of my driver but don't  see those
messages while system is still running in initrd stage.
The NASH shell keeps loading mine and other drivers. I can see the other
messages, like from e1000_main.c ( Link is Up). I can see the messages
output by  NASH (Loading driver XYZ, along with mine driver) but don't
see printk messages from my driver.
I tried to comment the  "setquiet"  in the /linuxrc script of my  initrd
image. Did not help me to get those printk messages on console. 
 
There is some troubleshooting I need to do for my driver(boot time).
Can someone tell me what different I have to do to get the
printk-messages from driver during  initrd/NASH  boot stage.

thanks
