Re: Delay in Printk Messages.

Try echo "7" > /proc/sys/kernel/printk to enable all console log levels.

The numbers are corresponding to below:

#define KERN_EMERG "<0>" /* system is unusable*/
#define KERN_ALERT "<1>" /* action must be taken immediately*/
#define KERN_CRIT "<2>" /* critical conditions*/
#define KERN_ERR "<3>" /* error conditions*/
#define KERN_WARNING "<4>" /* warning conditions*/
#define KERN_NOTICE "<5>" /* normal but significant condition*/
#define KERN_INFO "<6>" /* informational*/
#define KERN_DEBUG "<7>" /* debug-level messages*/

The default number is 4, which allows console to show messages only at
least in KERN_WARNING. That could be why you cannot see log in
KERN_INFO level.
