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. -- Warm Regards, Syam
