delay in booting due to consloe_unlock inprintk

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

 



HI All,

I am getting more than 1 sec delay during booting.
While registering console (for serial console ttys ), there is about 1 sec delay in executing the console_unlock() in printk.c

It was found that delay is occuring in call_console_drivers()
******************************
if (c == '\n') {
if (msg_level < 0) {
/*
* printk() has already given us loglevel tags in
* the buffer.  This code is here in case the
* log buffer has wrapped right round and scribbled
* on those tags
*/
msg_level = default_message_loglevel;
}
_call_console_drivers(start_print, cur_index, msg_level);    // if this part is commented, there is no delay observed?
*******************************


is there any way to find out what is causing the delay.

Syam
