Hi Greg, The SDRAM address range is 40020000-42000000, so the kernel dump does not show PC address at 4001fdac. Seems to me this is stack overflow problem? Is there any other way to trace it?

So disassemble the kernel and see what code this is: m68k-elf-objdump -d linux-2.6.x/vmlinux Regards Greg ev _______________________________________________ uClinux-dev mailing list [email protected] http://mailman.uclinux.org/mailman/listinfo/uclinux-dev This message was resent by [email protected] To unsubscribe see: http://mailman.uclinux.org/mailman/options/uclinux-dev
