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?
Look back through the stack frame and try and build up
a list of functions called through.

Hi Greg,
Here is the console dump. It happens when I use the telnetd, but
actually it can happens when any programming running on uClinux (like
PID 0 swapper process). Is there any other information I can provide
about this crash?
*** ILLEGAL INSTRUCTION *** FORMAT=4
Current process id is 42
BAD KERNEL TRAP: 00000000
PC: [<4001fdac>]
Looks like a kernel address. So disassemble the kernel and see
what code this is:
m68k-elf-objdump -d linux-2.6.x/vmlinux
