Thanks for your suggestion. I make a little change and redo the
ksymoops.
--------------------------
ksymoops 0.7c on i686 2.3.37. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.3.37/ (default)
-m /boot/System.map (specified)
No modules in ksyms, skipping objects
Warning (read_lsmod): no symbols in lsmod, is /proc/modules a valid
lsmod file?
Unable to handle kernel NULL pointer deference at virtual address
