Builds on POWER now fail fairly consistently due to this kernel bug:
https://bugzilla.redhat.com/show_bug.cgi?id=1518707
I'll keep trying, but the failure rate has gone up considerably in
recent weeks (perhaps additional builders were updated to broken
kernels?). I'm not even sure if it is below 100%.
The Fedora kernels have been fixed and are in testing now, so I think we
just have to wait. 8-(
Thanks,
