My mistake, sorry: kernel 3.15-rc2 crashes at boot, in the SLES12
Beta5 environment that I am using, before any module load attempt.

The problem happens with the SLES12 kernel of the day 3.12.17,
plus the backported ABIv2 patch set.  Boot fails with:
     kernel: ibmveth: no symbol version for TOC.
     kernel: ibmveth: Unknown symbol TOC. (err -22)
     kernel: scsi_mod: no symbol version for TOC.
     kernel: scsi_mod: Unknown symbol TOC. (err -22)

In the rescue shell, repeating a plain modprobe fails again:
     :/# modprobe scsi_mod
     modprobe: ERROR: could not insert 'scsi_mod': Invalid argument

And finally, modprobe succeeds with --force:
     :/# modprobe --force scsi_mod
     scsi_mod: module has bad taint, not creating trace events
