- Seems to have issues only on Xen kernel - Don't know if it is a regression from an earlier version, we have been using only SLES11 and SLES12 so far - regarding trying a kernel from different repo, I won't be able to try it in the next 2 weeks as schedule won't allow it. We were in a bind so we opted for vmware player for this server. We never had any issues with Xen and SLES11/12, and we were unpleasantly surprised with fragility of Leap (like the inability to unlock Gnome GUI session after it is locked due to inactivity).
