Error when compiling kernel linux-2.6.22 : make: ***[_modinst_post] Error 137
 

I'm compiling kernel Linux-2.6.22 version

When running command "make modules_install", I got following error:

..........
if [ -r System.map -a -x /sbin/depmod ]; then /sbin/depmod -ae -F System.map 2.6.22; fi
/bin/sh: line 1: 7567 Killed /sbin/depmod -ae -F System.map 2.6.22
make: *** [_modinst_post] Error 137

Please show me how to fix it.
Thanks a lot!
