We currently run as part of CI several workloads[1], among them LTP tests[2], and sometimes it's not pretty, because we encounter stability problems in Graphene+SGX even without the patchset. We'll pick some stable subset and will let know. Right now we'll have to retool CI for custom kernels, which will take some back and forth with uni's admins.
