loading modules

From: stefania magistrali <hidden>

Hi all!
I am working with a PowerPC 860T based board.
I have a problem with loading modules: I made:

make dep make clean make zImage  make modules  and make modules_install

to create my kernel and modules  , but when I try to load the module
hdlc.o with insmod, I have a segmentation fault. I am using busybox
version 0.60.3  and linux version 2.4.19pre6. Here I send the last part
of the strace sequence of the command "insmod  hdlc"
Can anyone help me?
Thanks very much in advance!
Stefania

This might be related to a powerpc-specific bug in the busybox
insmod implementation. Try the 0.60.4 release or use this patch:
