Hi all,

* After compiling 2.6.20-rc3 and typing "make modules_install" I get:
INSTALL **
..
if [ -r System.map -a -x /sbin/depmod ]; then /sbin/depmod -ae -F System.map \
2.6.20-rc3-1; fi
/bin/sh: line 1: 10727 Segmentation fault /sbin/depmod -ae -F System.map \
2.6.20-rc3-1
make: *** [_modinst_post] Error 139

* I found sbin/depmod tries to open a non-existent file before being killed:
$ strace /sbin/depmod -ae -F System.map 2.6.20-rc3-1
... (Opening
readlink("/lib/modules/2.6.20-rc3-1/source", "/", 1) = 1

close(4) = 0

O_DIRECTORY) = -1 ENOENT (No such file or directory)
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
+++ killed by SIGSEGV +++

I've compiled 2.6.20-rc3 several times before (I'm on a 20-rc3 now actually).
It's the first time to see this problem (maybe cause I changed the .conf file ?).

.conf file that caused the problem is gzipped and attached. Thanks ..
