Linux kernel reboot issue

Linux kernel reboot issue

[jimmy liu]

Our custom board is similar as EST8260. We use Linux
Kernel 2.4.25 from ftp://ftp.denx.de/pub/linux/. When
we type the reboot command or shutdown -r, we got the
following error messages. Does anybody has idea? 

The system is going down NOW !!
Sending SIGTERM to all processeTerminated
Sending SIGKILL to all processes.
Please stand by while rebooting the system.

Check your m8260_setup.c file for m8260_restart() and make sure the code
matches your flash configuration.  Specifically, the startaddr.

Other than that, did you look in your system map to check the PC against
the exception to find our which piece of code is causing this?

Your board may be similar, but it is obviously not identical  to  the
EST8260.  You  must  port  Linux  to your hardware, not just use some
"similar" board configuration.
