P4080DS kernel debugging feature

I am currently working on the P4080DS platform. In Kernel menuconfig, I enabled "Kernel debugging" and "Debug VM" features and compiled the kernel.


During kernel booting, the kernel hangs with a message "drivers/rtc/hctosys.c: unable to open rtc device (rtc0)"


RTC clock is also enabled in the kernel.


This is the kernel version that I use.

Linux p4080ds-p1 3.0.34-rt55-02404-gla39570 #1 SMP PREEMPT PATCH RT ppx GNU/Linux


Could anyone help me on this?  I can share more information if required.
