Hi,

I’m using autoyast for setting up our HPC nodes. We are using some additional software to access  
our file system (quantum STORNEXT).  
We have prepared a new installation source (http) with all files (system, system updates, sdk, sdk updates and compiler).  
After installing a node using autoyast with this repository everything seems to be fine, but when I try to  
install the stornext software (building a kernel module) I run into problems. Everything is build correctly (kernel module),  
the software is installed, but when I try to load the module the following error appears:

```auto

node31:~ # modprobe -v cvfs
insmod /lib/modules/3.12.49-11-default/extra/cvfs.ko 
modprobe: ERROR: could not insert 'cvfs': Exec format error

dmesg | tail -1 
[721.104497] module: cvfs: Unknown rela relocation: 4

```

I check the kernel version, compiler libs all seems to be the same (compared to a manually installed system).  
Any idea ?

Hi Peer,

it might have to do with some backport of changes related to [https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=b21ebf2fb4cd](https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=b21ebf2fb4cd) - regarding kernel and/or binutils. I haven’t checked the actual SLES source, but engineering should be able to tell if your systems are affected by that change (buzz word would be R\_X86\_64\_PLT32, which likely is that “unknown rela relocation 4”).

I recommend to open a service request for this, which should be the quickest way to get an answer from the SUSE engineering team.

Regards,  
J
