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.
