Subject: Error "Unknown relocation: 36" on module load on Sparc

Hello,

We in SCST project have a very strange problem on Sparc. Our main module 
scst.ko, if built as a module out of the kernel tree, can't be loaded 
and "modprobe scst" returns:

FATAL: Error inserting scst 
(/lib/modules/2.6.26-2-sparc64/extra/scst.ko): Invalid module format

The following message is immediately spit out by the kernel:
[ 1686.676534] module scst: Unknown relocation: 36

On x86 everything works fine. If SCST built inside the kernel, on Sparc 
it also works fine.

We completely stuck and have no idea what could be the cause. Googling 
also doesn't help much.

Could anybody point out a direction how to find the cause of the issue? 
I'm attaching Makefile we are using for you reference.

Thanks,
Vlad
